What would the semantics of nameof be in Python? Would it just be
lambda obj: obj.__name__? Or some fancy inspect-module style chain of
“try this, then that, then the other”? Or does it need to look at the
compiled source code context or something?
I think some wrapper around inspect.getmembers() would be the
easiest/best thing to do.
dict(inspect.getmembers(obj))['__name__']
With some error checking for the KeyError if inspect.getmembers can't
get a name for the object you passed in.
There are probably more performant ways to write this, but this was my
easy one-liner version.
And in case it's not clear, my point is:
Many things in Python don't have have names. For those that do, the
inspect module knows about them, so use it. And if there's something
that has a name that inspect currently doesn't recognize, then if we fix
inspect to understand the name of that object, everyone who uses inspect
would win.
