I'm pushing variably sized lists onto the stack, for example when called
in a scalar context the routine returns a single value, and a list when
called in a list context (or an empty list on error).  According to
perlxs if you are going to do that sort of thing you need to use PPCODE
instead of CODE:  Isn't that correct?
