Btw, this is not really reliable (i.e. always correct) right? Since $: 
might have been manipulated in between. Also the code above did not 
check the case when a file is required by absolute path.

To be more reliable, perhaps extend Kernel::require. Or always require 
with absolute path (but that's un-Rubic).
