Description

We can't use In/Out modifiers because that's a syntax error

class A[Out[T]]: ...
           ^
SyntaxError: invalid syntax

So what about semantic naming for type vars? in_T/out_T?

Research direction

Start by reproducing the reported SyntaxError for class A[Out[T]] and review the type-checker's handling of generic class declarations. Clarify whether the intended result is declaration-site In/Out syntax or semantic names such as in_T/out_T; done should include a decided syntax and corresponding behavior.
