I was trying to figure out exactly what metaclasses allow you to do,
and I came across the following quote:

 Metaclasses are deeper magic than 99% of users should ever worry
about. If you wonder whether you need them, you don't (the people who
actually need them know with certainty that they need them, and don't
need an explanation about why).
-- Python Guru Tim Peters

If you've got an example of something you want to do with metaclasses
in Ruby, post it here.  I'll bet you get a lot of suggestions that are
less "brain-melting," as the Python folks like to say.

Remember, you can do a lot by including Mixin modules.
