Bug #8841: Module#included_modules and prepended modules
https://bugs.ruby-lang.org/issues/8841

Author: marcandre (Marc-Andre Lafortune)
Status: Open

The documentation for Module#included_modules currently states "Returns the list of modules included in +mod+."

This was never perfectly accurate, as the list also contains modules included in +mod+'s ancestors.

It now also includes prepended modules.

This is consistent with `include?` that returns true for prepended modules, but not quite consistent with `included` that does not get called for prepended modules.

Matz, could you confirm that current behavior is what you want?

If so, we should fix the documentation of `include?` and `included_modules`.
