I'm going to repost after i figure this one out, the problem with my 
first post (and i apologize for posting inaccurate code), was that the 
"#{m.call}" was getting evaluated in the 'module_eval( "..." )' and it 
wasn't actually getting called when rand got called.

Kernel.module_eval( "def rand; #{m.call}; end" )

Will have rand return the value of m.call. It will always return the 
same thing, because m.call is evaluated in the String, and not when rand 
is called.

     m = proc { 50 }
     def rand; #{m.call}; end

is the same as:

     def rand; 50; end

working on a solution,
