Comment (by nthiery):
Nice! this looks good!
Just being curious: does this play well with @cached_method? That is, can
we do something like:
{{{
@conditionally_defined(...)
@cached_method
def ...
}}}
Could you further implement the {{{has="..."}}} (or {{{hasattr="..."}}})
argument to {{{@conditionally_defined}}} as in the example of the ticket
description?
The ticket description also mentions conditionally defined nested classes.
I actually don't remember putting this there; did I really? Do we have any
strong use case? Otherwise I guess we can postpone the feature.
Thanks!
