In something like C++ you could create a scope like so:

{
	// Do something neat here
}

I was wondering about having or maybe even requiring a scope keyword, which might look like this:

scope
{
	// Do something neat here
}

This seems even more relevant in an indentation sensitive language like python:

scope:
	pass

Interested to hear any opinions, TIA.

    What’s the intention and use case for this?

    Only for empty, unlabeled, untyped scopes? Or would I write

    function a() scope {}

    Is it necessary for scope-ending cleanup of resources? If so, I would consider whether there are not better solutions for those.

    Is it for code structuring? I would also consider what use a scope keyword has then, and what the alternatives are.

    I don’t see how adding a scope label helps with anything.

      To be honest, the only use case I really thought of was something like unlocking a mutex at the end of a scope or maybe a file.

        In that case managed languages like python and java combine that functionality with try blocks. This is generally called try with resources.
        C# has the using keyword that just uses local scope.

        The commonality between them is declaring which resource is managed, not just everything is a scope. Imagine you wanted to manage one resource and return another.
