The non-unit tuples weren't being pretty printed with parens. Is the user supposed to add parens manually
with the parentheses expression?

If not, this patch adds them in the pretty printer.

Thanks travitch,

The intention is that the parser should insert a Paren into the AST.

If you generate the AST yourself, without parsing some input source, then you will need to add the Paren constructors where needed.
