kint | Kint - a powerful and modern PHP debugging tool | Code Inspection library

I have a class that essentially runs through a matching pair of arrays to do some error correction:

Background (Intro)
Kint is a PHP debugging tool that works as a more powerful replacement to PHP's var_dump(), print_r(), and debug_backtrace(). One unusual -- for PHP at least -- feature of Kint is the ability to use real-time modifiers in the form of operands. Here is what the manual states about that feature:

There are a couple of real-time modifiers you can use:

• ~d($var) this call will output in plain text format.
• +d($var) will disregard depth level limits and output everything. Careful, this can hang your browser on large objects!
• !d($var) will expand the output automatically.
• -d($var) will attempt to ob_clean the previous output and flush after printing.
• You can combine modifiers too: ~+d($var)

There is an older exiting SO question that is similar to this question if you need more information.

Questions

1. How does Kint add these operands without triggering a PHP error?
2. How can I emulate/capture any calls that use these operands?

Without loading Kint if you attempt to use these operands or create your own functions to capture Kint operand calls you get Fatal error: Uncaught Error: Unsupported operand types.

Important: I am using the kint.phar file and I'm not using composer or any kind of CLI usage.

My Use Case (Please don't get distracted from the Questions)
I'm adding this information for those that are curious and to further clarify my questions. I sincerely want to learn and understand HOW they are doing this and would appreciate answers to that end. This question is not about defending / critiquing / disagreeing with my use case:

For security and optimization I am creating a fake (empty) Kint class that loads when my site is in production mode. This ensures that any Kint calls left in the code on accident do not trigger fatal errors, can never print anything out, and uses less resources compared to loading the real Kint class.

I know you can disable Kint with Kint::$enabled_mode = false; but lets not focus on that. Here is the code I use to fake the Kint class. All that is missing is capturing calls that use these non-standard operands:

I'm trying to implement visitor pattern for n-ary tree mutation. Currently i'm stuck with shared pointers. Mutator operates on each tree node and can return either pointer to a node itself w/o any changes, or a pointer to a copy of modified node (original node cannot be modified directly). But obviously i can't build a shared pointer from a raw pointer inside Visit method, neither i can't make a shared pointer from this inside a Mutate method. The only idea that comes into my mind, is to create another class which will be holding pointer and pass this class pointer to visitor instead, but perhaps there is a better solution?

I have react hooks section in which user can edit input fields, there are hundreds of inputs that is why I need to use redux (newbie to redux though),

so far I have this

I'm having some issues, I'm loading some nodes and i want to get some values field, this is how is my field

I'm loading my nodes like this:

Here is where I'm at:

I downloaded the group module, created custom fields for the group, then on the page itself I overrided it with a twig template (page--group.html.twig). The question now becomes, how do I pass down the custom fields from group (machine name of a field is "group_picture") to the twig template of page--group.html.twig?

I used kint() to see if anything was being passed down from the group, but nothing was being passed down. What am I missing here?

I am new to PHP programming and I am trying to teach myself WordPress theme development for fun and I am using PhpStorm as my IDE.

I am trying to better understand the inner-workings of WordPress and I am running into a roadblock on something.

I have a sandbox plugin that I created to use to play around with WordPress.

In my “wp-content/plugins/sandbox/sandbox.php” file, I am just running basic PHP code to help me get used to the language as it relates to WordPress.

Also, I installed both Kint and Whoops using Composer to help with debugging.

Now that I got that out of the way, here is what I am doing:

Code #1

I am completely new to PHP and I am trying to teach myself here and play with the prospect of creating my very own WordPress theme - YAY!

Anyway, I am running into a roadblock here and I am not certain if this is just the IDE I am using (PhpStorm), or if it is something else.

Here is what I am seeing in PhpStorm:

When I use Kint, it shows that the namespace is defined as shown in the screenshot above (namespace SavvyPro\Sandbox):

I am trying to get the image back from the tensor I created earlier and visualize it, However, the resulting image is distorted/garbage it seems. This is how I convert a CV_8UC3 into the corresponding at::Tensor:
