You've also removed the parse_subsignature() function, and that's
a problem.  It was intended to be an API function, once signatures are
no longer experimental.  It needs to be an API function in order to make
it feasible for an XS module to parse the top-level "sub" syntax itself,
which is needed as a base on which to create any syntactic variation of
subroutine syntax.  It doesn't matter which way the actual parsing is
done; just the interface needs to remain.
