Yep, sure enough it seems to work (which is obviously a very good
thing)! I'm relying on ruby-doc.org from work and looks like the
source doc they're using is outdated/incorrect/inaccurate:
obj.extend:
Adds to obj the instance methods from each module given as a
parameter.
mod.extend_object:
Extends the specified object by adding this module?s constants and
methods (which are added as singleton methods).
