Functions or modules?

[Giancarlo Niccolai]

I am starting to port the core module, and while reviewing things like
dirMake and fileRename, I was wondering whether:
1) Keep the old functions as they are
2) Create a class or namespace for the functions, like dir.make()... but
keep them in the core module.
3) Move them in another module, like, the dir module, so that

import from dir in dir

dir.make(...)

would do.

Suggestions?
