That's a legal long dot but still a Perl syntax error because you've
got two terms in a row. A postfix still isn't allowed to have space
before it, so the backslash must be the first thing.

: .foo();
It does fix that bug, since \ quotes any whitespace, not just newline.

Seems so to me too. I don't see much downside to \. as a long dot.
