Heh, are you wanting to do the same that I want to? :)

(See http://noegnud.sourceforge.net/flgr/proc_source.rb -- I'm doing 
lots of manual parsing there however.)

If we're adding this we might as well think about adding a character 
index for both the start and the finish which would allow us to find the 
correct source code even if there are multiple Procs on the same line.

(Plus if we had that, we wouldn't need to do any manual parsing at all.)

Oh, and it would be great if there was a way to overload eval() without 
breaking anything. Currently if one does that this won't work any more: 
a = 5; eval "a"

But we might not get a way to do that before the eval:pre-style hooks 
anyway.
