As explained in microsoft/TypeScript#2548, the following code is not correct when useDefineForClassFields: false, which is the default for targets before ES2021.

const x = 1
class C {
    p = x
    constructor(x: string) { }
}

However, when useDefineForClassFields: true, there shouldn't be an error here.

Expected: No error 2301 on `private p =

When doing division and modulo operation with constant or immutable denominator it is possible to only do compile-time denominator check and skip runtime checks.

Consider following contracts:

pragma solidity 0.8.15;

uint256 constant _MODULE = 17;

contract C1 {
    function f(uint256 a) external pure returns(uint256) {
        return a % _MODULE;
    }
}

contract C2 

I'm Writing a ThemeColor Plugin, use Visitor.

In fn:visitColor , node.parent sometimes is null (box-shadow:0 0 0 1px #999 inset). I can't find the parent Declaration Node of Color Node.
so I want to [less.js/lib/less/visitors/visitor.js Visitor.prototype.visit](https://github.com/less/less.js/blob/0e268598c8327b9e8d36d9bb2edfde95d8d787be/packages/less/src/less/visitors/visitor.js

I can't find any documentation or thorough tests of the path substitution performed by compiler/options/pathSubs.

From looking at the code, these are the substitutions:

• $nim: global nim prefix directory path
• $lib: stdlib directory path
• $home: user's home directory path
• $config: I think this is the directory path to the either the nimscript calling
  `compiler/options/path

Many existing test cases check that pickle.dumps and pickle.loads of a given type return the exact same value. Almost failed pickle test in RustPython, lack __reduce__ method.

• arrayiterator.__reduce__ (test_array::test_iterator_pickle)
• filter.__reduce__ (test_builtin::test_filter_pickle) — #3732
• map.__reduce__ (test_builtin::test_map_pickle) — #3734

Having a callback for when the selected element is changed would be useful, for similar reasons to TextEdit/LineEdit: validation, updating buffers, or the rest. I imagine that it would be something like selected(int) with int being the index, though LineEdit emits a simple callback without arguments so there may be a tradeoff I'm missing (an int should be easier to pass around on the oth
