Can you add a spec somehow?

@bew it's there, see the diff.

I'm not sure this is right. There should not really be an issue with accessing out as local variable. #6042 could be fixed differently.

I'm pretty sure @makenowjust didn't just forget to add a restriction to out in #5930.

out as a local variable should be forbidden. out is a keyword and it can be confused with the out var syntax.

That said, out taken as a keyword just for interacting with C seems like a bad design choice.

Basically...

out = 1
foo(out) # Error: expecting variable or instance variable after out

That's why out should not work for local variables, because you can't pass them to other methods.

Then all keywords should be forbidden?

out var could be confused with a method call, but not really with a local variable called out.

If out is not followed by a variable name, it's not a keyword.

@straight-shoota That's just confusing, but if someone wants to implement that, please go ahead (and revert this PR).

@straight-shoota Yes, I did't forget to add out. However, @asterite's opinion makes a sense to me. I have no disagreement with this PR.
