This might be a good question to ask on ruby-talk.

I suggested a way to do something like this at

http://ruby-talk.org/100429

Briefly, the Script.load method loads a file and returns a module which 
you can use to access the top-level constants and methods defined in the 
file.

Script also defines #load and #require methods so that calling load and 
require from your script file first tries to find files relative to the 
script file, and, if found, wraps their top level constants and methods 
in the same module. If the files are not found, it falls back to 
Kernel#load and #require.

It's a trivial little piece of code, but I gave it a home at:
