Hmm.  Maybe we could go with :{+...} or the like?

Sorry, that is just horrid.  foo/bar means division, and "foo/bar"
is simply an identifier per SQL standard, so you can't squeeze that
in without breaking an ocean of stuff.  Plus, there are many use-cases
where there's no reason to put a slash in a relative filename.
