The  point  is,  that  internally  PARSE would be forced to do the
equivalent of:

   [any [a | b | c | skip]]

so  even  if it could be a bit faster than the above I don't think
it  would  be  of  great  help.  More  readable,  maybe... so it's
something I could add to compile-rules, if I get some time to work
on it.

In  this  particular  case,  I wouldn't use this construct at all,
since  it's  much better to have a more complete grammar (that can
make  distinction  between  href=  in  a  tag and outside of a tag
etc.), IMHO.

Regards,
   Gabriele.
