Oh yes! A programmer needs to need a special driver's license to
overload operators ;) The concept isn't difficult, but using it
sensibly (and not for 'fun') is tricky.
Another use of defining __call that isn't such a good idea: for an
object to return its iterator
for val in obj() do ... end
Much better to say obj:iter() explicitly.
