This is "easier to ask forgiveness than permission" (EAFP). This tends to
be more Pythonic (and thus, preferred). You don't *really* care what the
version just, but whether or not the string module has a Template object.
Besides, what if some bright admin at some customer decides to backport the
Template implementation to their 2.4 installation? The first form would
load your compatibility version, probably not what they were hoping when
they put in the effort to backport.
That was the kind of reasoning I'm looking for. I'll stick with the
pythonic try/except approach then.
