Right. Which is why I suggest only changing the parsing in cases where it is
currently a syntax error: in other words try to parse using the current rules,
but if these rules guess that {} is an anonymous hash constructor and this
gives a syntax error, backtrack and parse it as an empty block instead.
That wouldn't break any existing code, but I don't know how practical it is.
