Not dirty, just harder in Python than you apparently believe.  If you were
to, say, offhandedly suggest that Python "should do" this and that it's no
trouble at all, the glaring reaction you get should probably be taken more
personally than technically <wink>.

Ahem -- functional languages deliberately constrain their type systems to
make type inference tractable.  Python doesn't.

Well, in *that* case ...
