Hey, that's a nice trick. Thanks!

BTW, what's here isn't an official feature? I do "ri Kernel#require" and 
(I think) it describes everything needed to make this work: Ruby first 
looks for an .rb file (this enables us to inject our loader script), and 
then it's possible to explicitly load a .so (or .dll). So why isn't your 
trick future-proof?
