Hi Dan, Hi Factor List
Last night I was looking for a pattern matching library and found your
post on extra/inverse. I just wanted to check that I'm not missing a trick:
I want to match 3 elt sequences, but after the match I want the seq as
it was (i.e. not destructured). I'm doing the following:
e.g. matching { 1 "hello" 3 }
{
! this one doesn't match
{ [ >r >r >fixnum r> >fixnum r> >string 3array ] [ 3array
dosomething ] }
! this one matches
{ [ >r >r >fixnum r> >string r> >fixnum 3array ] [ 3array
dosomething2 ] }
} switch
Is this a reasonable way to achieve this with inverse or am I
overlooking something simpler?
Many thanks,
Phil
