Rename TypeExpr to TypeForm #475
Conversation
No backwards compatibility required because we never released TypeExpr. Also took the opportunity to expand the docstring.

This phrasing is subtly confusing in the same way that earlier drafts of the PEP were. A TypeForm doesn't represent a type expression. It represents the set of runtime objects that encode the information in a type expression. This is the reason we moved away from the TypeExpr terminology. I recommend using the phrasing from the latest draft of the PEP. I tried hard to make that phrasing as clear as possible to avoid such confusion.

Thanks, I rewrote the docstring to align with the Specification section of PEP 747.
