'mean' stands for anything.  I should have called it 'some_func'.  You
can't just change its meaning.  In particular, you can't change the
methods in the ruby standard library.  (Well, you can, but you'll be
in danger of receiving a painful retributive wedgie from those who use
your code.  Perhaps even an atomic one.)

You can always write wrappers which convert a given method or lambda
to a one-argument lambda expecting an array.  But this is just another
kind of Lisp emulation in Ruby, taking non-homogeneous primitives and
making them homogeneous.
