Hmm. Well, that doesn't sound like a productive way forward to me,
but as I say I'm neither the most intelligent nor the most experienced
programmer here, so maybe it's the right way to go. I guess in that
case, my current stance is -1 on this, both in added syntax and
decorator form, with the caveat that I'd be happy to change my vote
if
anybody can produce code that does this without mangling performance
or
introspection.
