Perl 5 makes the distinction between $^X (the interpreter name) and $0
(the script name)

Perl 5 also puts some effort into seeing if it can get a fully qualified
path for the interpreter from the OS. Certainly this is do-able on Solaris,
on Linux given /proc, and on FreeBSD given /proc and a following wind
(at least on FreeBSD 4 where there is a bug). I think it's do-able on Win32
too.

Would we want to try to do this?
