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

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.
