yell | PHP package to make your objects | Reflection library

I am working on a symbolic algebra system. I'm currently looking at how to carry out polynomial addition/multiplication from a binary parse tree. I will later consider this to be a general ring.

Parsing is not relevant here -- this intended to be the output of parsing. The parse tree that is formed. If something could be improved here, I'm certainly happy to learn about that too.

I 'feel' that this tree structure could be folded/crushed, yet I'm not too clear on how to go about it. I believe I can hack something together, but as I'm still learning Haskell, I wanted to learn what the more advanced users would do.

Below is relevant code background.

My two relevant data declarations are:

I'm making a server plugin that kicks players when they die. I've got that all sorted out, but I want to be able to toggle it on and off. I've seen to use a boolean, but it yells at me when I put @EventHandler inside of a one, I don't think I'm doing it right... So I guess the question is really, is there a way to make it so when "/kdoff" is executed, @EventHandler isn't until "/kd" is executed. I feel like there's something you can do with onDisable() but I'm not fully sure how those work to be honest.

Let's say I have a custom MyArray class that extends upon the builtin Array class, how should I type so that myMap(myArr: MyArray, ) can correctly infer the return type as MyArray, instead of the builtin Array?

PS: I want this type declaration to be as general as possible, which is why I didn't simply overload the map method. That way, I can easily change the signature for type variable Arr in myArr to Iterable, and this can also be used on other builtin/custom classes like Set that implements the Iterable Protocol. Right now the best I could do is to have the user specify their desired return type as a generic function variable.

First time using typescript, and would like to know how to best deal with this situation.

I have some json data coming from API, say

Before you tell me that the way to run .fsx scripts in .NETCore/.NET5(or higher) is dotnet fsi, FYI: I know that already. I just can't upgrade yet, so I'm still running my .fsx scripts with the good-old .NET 4.x Framework.

To do this, and to run them under GithubActions CI, I had this handy fsi.bat file:

Very noob question, but how can I create a form in APEX that is not based on a database table?

For example, I am looking to create a "Change Password" form that consists of 3 fields:

• USERNAME (display only, value populated with &APP_USER. from URL)
• NEW_PSWD
• CONFIRM_PSWD

None of these fields will be saved to the database, so not sure how to handle the SOURCE for the underlying form. My first thought was to just use a SQL statement like this:

I have a test that says "After approx X concurrent connections, I should see socket hangups since my service will stop answering someone hammering me."

This works pretty well after a lot of painful trial and error, but because I am using await Promise.all(myrequests) the first time I see a hangup it throws a socket hang up exception.

This works, but causes some error messages, since my routine for hanging up does some debug logging, and the test is over at this point.

What's the best way to say: "wait for all of these, even when they throw errors?"

My jest/supertest problem block looks something like:

I have the following endpoint:

I'm doing a wrapper for an API and I have my json models which I would map into my entity models with MapsterMapper.

I have tried to simply do jsonModel.Adapt() with EntityModel looking like this:
