> I'm not really a fan of autoload

What do you dislike about it?

FWIW, I saw your questions on twitter.  Yes, using autoload blows away the method cache, but so does require: any method that causes new code to get loaded will blow away the method cache.  I'm not terribly concerned since this is while loading the configuration and spec files and everything, before rspec runs any specs.

Anyhow, sure, we can leave it as-is for this PR.
