In Ruby, you simply include files.
I don't know how they are implemented in Ruby, but I know them from PHP, and includes can turn into an include hell as well, but I'll agree that modularization has, at least, not an obvious solution and it could be rethougt.
Nevertheless, Python still has a cleaner, nicer syntax than Ruby, more general purpose libraries, and a larger userbase, and it's a better multiparadigm language where you can work procedurally, functionally or object-oriented, without making either your religion (which is bad because you should use the right tool for every job).
