[New-bugs-announce] [issue33517] dataclasses: Add the field type to Field repr

[Eric V. Smith]

New submission from Eric V. Smith <eric at trueblade.com>:

With the recent (and ongoing) change to string annotations, it's no longer obvious what the type of a field is (normal, ClassVar, or InitVar).

I propose exposing the heretofore undocumented _field_type to the repr. Instead of writing it directly, I'm going to make it say one of:

_field_type=_FIELD
_field_type=_FIELD_CLASSVAR
_field_type=_FIELD_INITVAR

This is because it's an object reference, and would otherwise look like:

_field_type=<object object at 0x10cc5f1f0>

Which is all but useless.
