I don't recall Guido being opposed when PEP 362 was first being
discussed (keeping in mind that was more than 2 years ago, so he's quite
entitled to have changed his mind in the meantime!).

That said, it's a sensible, largely straightforward idea, and by
creating the object lazily it doesn't even have to incur a runtime cost
in programs that don't do much introspection.

I think the main problem leading to the current lack of movement on the
PEP is that the existing inspect module is good enough for most
practical purposes (which are fairly rare in the first place), so this
isn't perceived as a huge gain even for the folks that are interested in
introspection.

Cheers,
Nick.
