Here's a stab at a (relatively) simple approach to the function portion:


However, this does not expose __function__ in the locals.  Instead it
puts f_func in the frame object.  Thus it provides the functionality,
but doesn't invite abuse.  And whether you like it or hate it, it's
exactly what I've been looking for.


p.s. I tried doing it with a closure and, while it worked, I didn't
like it.  I will say that I came away with a _much_ better
understanding of the CPython implementation (and gdb :).  I feel much
better about the f_func solution, particularly since we're really
looking for the function associated with a frame.  Trying to
artificially force  __function__ into the frame's locals just didn't
feel right.
