[Chicago-talk] faster -h

So I have this Perl program that uses some hefty modules and as a result
it takes a second or two just to get going. Most of the time I don't
care because it's relatively long running and the loading time isn't
noticeable. However, it's annoying to have to wait when I just want
usage information. So I'm wondering if there's some way to do the
GetOptions stuff up front and then avoid the "use SuchAndSuch;" when I
find a -h or usage violation.
Any ideas?
Just to make things a bit more concrete:
$ ./pctrl -h
with all the modules: 2.105 seconds
with a minimal set of modules: 0.318 seconds
