QUESTION
In Data.Type.Equality there are two type-level equalities defined: :~: and :~~:. They are said to represent homogenous and heterogenous equality respectively, but I don't really see any differences between them. What is it?
To be honest I don't see a way for having a real heterogenous equality in Haskell type, due to the strict border between values, types and kinds in the typesystem.
...ANSWER
Answered 2022-Feb-24 at 12:00The difference is in their kinds:
QUESTION
In my other question, How to use a static method as a callback in c++, people solved my practical problem, then suggested I take a different approach in general to follow best practice. I would like a better understanding of why.
This example uses a comparator, but I would really like to understand if there is a general rule for functional programming (for example perhaps also aggregator functions related to a class etc.)
Example use case for a comparator function:
...ANSWER
Answered 2021-Dec-04 at 15:23Firstly, note that if you just want a > comparator, there are std::greater<> and std::greater (the former is usually superior).

QUESTION
Why is this example ok in Typescript:
...ANSWER
Answered 2021-Oct-29 at 12:41The behavior in second example is called excess property checking
TypeScript takes the stance that there’s probably a bug in this code. Object literals get special treatment and undergo excess property checking when assigning them to other variables, or passing them as arguments. If an object literal has any properties that the “target type” doesn’t have, you’ll get an error
This applies only to object literals. Assigning variable with extra properties is still allowed:
QUESTION
Angular 12 seems to have migrated to Webpack 5 and that seems to make the build using erdJs not work, at least in my case.
I've managed to find a few workarounds, including installing crypto-browserify, stream-browserify and path-browserify and using those in my tsconfig.json paths but I still seem to be missing "fs" and getting this Error when running ng build or ng serve
/node_modules/@elrondnetwork/bls-wasm/bls_c.js:54:30-43 - Error: Module not found: Error: Can't resolve 'fs' in '...\node_modules\@elrondnetwork\bls-wasm'.
This error occurs 5 times in 4 other files located in erdjs:
...ANSWER
Answered 2021-Oct-12 at 18:40For others coming to this question in the future. Currently there is no way to use the erdjs npm package in an angular project.
The current workaround involves compiling the erdjs package to its browser version and using that as an asset in the project.
You can compile it yourself by using yarn run compile-browser
The workaround is further described and showcased here: https://github.com/ElrondNetwork/elrond-sdk-erdjs/issues/79#issuecomment-940872053
QUESTION
I recently got a runtime TypeError for something I think should be possible to catch during compile time with TypeScript. Here is the code:
...ANSWER
Answered 2021-Jun-21 at 13:40Your first type of MyObject is fine, but when you try to access a property on it, you can not know beforehand if it is defined or not. In this case, you can use optional chaining.
QUESTION
In my typescript program (code below) I define two base types (Player, State) and then a few nested Record types used as mappings.
I then in a typed function create an instance of one of these records based on an existing instance of the nested record.
...ANSWER
Answered 2021-Apr-15 at 17:52The type error is from your nextStates variable as you haven't specified it's type so it's inferred as {} when you define it as the empty object.
You can use a Partial type only for your nextStates variable to allow it to start off empty, but you will need a way to tell the compiler when the full PlayerStates object has been created using a guard. Here's an example:

Raku mixins have two (or more) natures, combining several values in the same container, or values along with roles. However, there is not, as far as I can tell, a straightforward way to check for "mixinity" in a variable that has not been created by you.
This might be a trick
