PS Can I echo Guido's plea that people don't derail this PEP by trying
to shoehorn deferred-evaluation-objects (or whatever you want to call
them) into it? As Chris A says, that's a separate idea and should go
into a separate PEP. If I need a screwdriver, I buy a screwdriver,
not an expensive Swiss Army knife.
As I've said before, I disagree with this. If you're going to introduce
this feature, you need some way of building an inspect.Signature object
that refers to the code to be executed. My concern is that if we add
something that has deferred evaluation of code, but we don't think of
how it might interact with other future uses of deferred evaluation, we
might not be able to merge the two ideas.
Maybe there's something that could be factored out of PEP 649 (Deferred
Evaluation Of Annotations Using Descriptors) that could be used with PEP
671?
That said, I'm still -1 on PEP 671.
