That is what I had in mind, i.e., to separate the issue of how
to get the standard POSIX shell from the more general issue of
how to support various other interpreters (Perl, etc.).  The latter
interpreters are pretty well outside the scope of POSIX.

Using a special syntax that cannot be interpreted as a path name
to denote a POSIX-compliant shell would eliminate the possibilty
of conflict with a given existing implementation or application's
assumptions about the meaning of any particular pathname and would
eliminate the issue of whether the system even supports conventional
Unix pathnames.

This would require a small addition to the loader, to recognize
the special syntax, and would only be useful to new applications.
