+1 from me on this one.

Something it could be useful to try to add, if possible: So far, it
seems that this create block can only create class-like things (objects
with a name, potentially bases, and a namespace). Is there a natural way
to extend this to other things, so that function creation can be
modified? For example:

create tracer fib(x):
    # Return appropriate data here
    pass

tracer could create a function that logs its entry and exit; behavior
could be modifiable at run time so that tracer can go away into oblivion.

Given the current semantics of create, this wouldn't work. What would be
 reasonable syntax and semantics to make something like this possible?

Maybe this would need to be a separate PEP. But it seems at least
somewhat related.
