Reading this discussion, I'm getting the feeling that filename
literals are increasingly getting magical, something that I don't
think is a good development. The only sane way to deal with filenames
is treating them as opaque binary strings, making any more assumptions
is bound to get you into trouble. I don't want to deal with Windows'
strange restrictions on characters when I'm working on Linux. I don't
want to deal with any other platform's particularities either.
Portability should be positive, not negative IMNSHO.

As for comparing paths: reimplementing logic that belongs to the
filesystem sounds like really Bad Idea™ to me. Two paths can't be
reliably compared without choosing to make some explicit assumptions,
and I don't think Perl should make such choices for the programmer.
