That won't work because it creates ambiguities in the package spec
syntax.  How can one tell if a package spec or a file name was passed
with 100% accuracy?  You can't, and we'd have to use a heuristic that
would surely fail in some awful way for someone.  It's best for this
to be a separate argument.
