I personally find "3(3)" to be a rather odd beast myself. However, in Lua4
(with its tag methods) one could redefine the "function" tag method of
numbers to have some desired meaning. So:
    a=3
    a(4)
would actually be executable code, while:
    3(4)
remained illegal. Totally inconsitent.


In Lua5 with its metatables the nature of things seems to have changed, so
I'm not sure what is now most natural way. Regardless, one *should* be able
to have:
    function(a) return a end (123)
