Or a plus as I think Ian suggested at some point: foo-bar-0.1.2+bar+foo.
There is, however, another good reason for not using a dash to
separate name and version. Package names can contain digits. I'm not
sure if they can or should contain dots, but given "foo-3", you don't
know whether it refers to "package foo, version 3" or "package foo-3
without version"... Maybe it's not problematic enough to worry about,
