I read it just fine the first time.

It's not nicer to people reading the code and wondering why, or to 
people who use it as a module and execute less-well-tested code paths, 
and I doubt it's a significant addition to boot time to do things in the 
normal way.

I'm not particularly worried about the code going on strike because 
we're not being "nice" to it.
