Ugh. Having the call happen on every object creation sounds even uglier. 
It seems it's best to roll our own. Probably a lazily initialized global 
static object that you can add functors to before main() and then run 
all functors of that object in main().

It seems the mailing list marks my posts as spam now. Probably because 
I'm using gmane? I'm sending this one without gmane, let's see if it 
makes it through unscathed.
