In most cases enums with _convert_ are used to replace old module
globals. They are accessible as module_name.member_name and always used
as mod

I'm just trying to present an argument that if the str() of an enum was

Well, we're still early enough in the 3.10 cycle we can make that change
That would be more palatable if it wasn't so common to use manually
assigned numerical values (as most of the examples in the enum module docs
do) or the default auto().

Okay, let me take a shot at this.
I actually like the status quo for regular enums, when repr() shows the
type, name and value, and str() shows "classname.flagname", so I'd stick to
that for converted flags. Even though this violates the rule of thumb that
repr() should look like a valid expressio
