Seems a little wierd :-), but,
that shebang line is there for the invoking program (usually the shell)
to decide what to run, apache and things like that also listen here,

afaik csh, tcsh, zsh and tclsh will also do the same.

If you are feeling particularly wierd then you 'can' use perl as the
shell, (perlsh?)
