Dropping the fn keyword causes no ambiguities in the grammar. It's easy to parse (both for humans and the compiler) because all the other declarations start with a keyword (currently: type, trait).
Adding constant declarations should also not be a problem, we can decide whether we're parsing a function or a constant based on the left paren.
