Points + AND - for being clever, though. This is one of the times when
I *feel* like I'm inefficient in lua:

local the_type = type(foo)

if the_type == 'table' then
  --- something
elseif type == 'number' then
--- blah

or some other/better example. I don't know if it *is* slow, however.
I'm not qualified to judge `orif` innovative or otherwise, but given
the volume of Sonic's proposals, I was surprised to find myself
intrigued by this one. FWIW
