I thought that would be pretty useful, but playing around with it, it
seems string literals are more special than numbers:

> function p(s) print(s); return p; end
> p "hi" "bye" "gone"
hi
bye
gone

stdin:1: unexpected symbol near '2'

hi
2
gone
> p 2
stdin:1: '=' expected near '2'


I thought that both numbers and strings were literals, but after some
reading through the manual, I see there is only one kind of literal, a
literal string.

I guess this is a legacy of lua as data description language? Would
things break terribly if any of {}, "", and Number could be passed as an
argument expression without parentheses?
