Subject: Module/file-scoped "global" variables?

Hello,

I have a file with some functions which share some common variables. I 
want to have these functions visible in whole program (or at least in 
some classes by making a module from the file and mix it into these 
classes), but I'd like to make shared variables remain unvisible to the 
rest of the program. Is it possible in Ruby?

Thanks,

P.
