In most cases, I've come to prefer lazy initalization (via a module-level 
@property) over module ctors because:

1. If it never actually gets used, you avoid adding extra processing at 
startup merely because you imported some module.

2. It decreases the risk of hitting the dreaded cyclic-module-dependency 
error (major PITA).

And if you do want to throw away #1 and force initialization upon startup, 
you can still do that by simply accessing it at the beginning of main.

I've always felt module ctors were a great idea, but after hitting the 
cyclic dependency issue enough times (or even just the first time), I've 
come to think they're, unfortunately, best avoided.
