module() public

Attempts to locate the included module object. Returns the name if not known.

The scoping rules of Ruby to resolve the name of an included module are:

  • first look into the children of the current context;

  • if not found, look into the children of included modules, in reverse inclusion order;

  • if still not found, go up the hierarchy of names.

This method has O(n!) behavior when the module calling include is referencing nonexistent modules. Avoid calling #module until after all the files are parsed. This behavior is due to ruby’s constant lookup behavior.

As of the beginning of October, 2011, no gem includes nonexistent modules.
