lib Update Request

Description

Tried running multiple unit tests using isoltest like so:

sergiuiacob@Sergius-MacBook-Pro solidity % build/test/tools/isoltest --test "yulSyntaxTests/*;objectCompiler/*"
Unhandled exception caught.
/solidity/test/tools/IsolTestOptions.cpp(99): Throw in function virtual void solidity::test::IsolTestOptions::validate() const
Dynamic exception type: boost::wrapexcept<soli

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 expected ? to not overwrite the query, but to merge. The docs of the proc use the word "concatenate" which implies that this is how the proc should work, but the implementation overwrites the query instead of concatenating.

See e.g. #2570. Some of the unit tests there with "wrong error message" should be somewhat easy to fix - just correct the error message we have to match CPython's. Others might be trickier, since you'll need to add diagnostics to recognize bad syntax and give a more detailed error than "unexpected token". Also, I think around half of them could be fixed just by adding "invalid syntax" in the messa

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
