And in Ruby, you can do :operator, for example:

        irb(main):002:0> (1..10).reduce(:*)
        => 3628800

After looking at these and thinking more about it, I would probably prefer
to trade concise for explicit and use Python's operator.mul. Lua's
explicitness is one of the reasons I prefer it to Ruby now. YMMV
obviously.
