Literal values and __call

[John Erling Blad <jeblad@...>]

I wonder if the following could be changed

  args ::=  ‘(’ [explist] ‘)’ | tableconstructor | LiteralString

It is in the doc [1] and is somewhat limiting. It would be better if
it included all literal values, and I can't see how this could be a
problem, but perhaps there are some other reason why this is
disallowed?
