5/18    In how many languages can you say "stick your head in a pig"?
        Collect them all here and we shall rival the x = 3 list...

        UNIX csh: head $user >> /dev/pig
        60a OOP Scheme: (ask you 'insert-head pig)
        C:   insert(Listtype pig, Listelement yourhead);
         [This totally misses the point.  It's not OO
          or nearly as abstract as ~xxxxxxxx/pig.c]

                                is better than
                    ask2(you, stick, "head", pig);
                /* really the same as...
                   you->stick(you, "head", pig);
                        [NOT.  Try actually evaluating that.]
                   See ~xxxxxxxx/pig.c for details..... */
                Ever hear of varargs, Dan?  I thought not.
                These still pale compared to the old vanilla:

                       (*(you->insert))(head, pig)

        C++:    you->insert(head, pig); /* note the simpler notation */
                                                Note your mom...
                                                        \_ note my grandmother
        perl:   $pig = $body{head}  <--- BZZT!  Wrong.  Try...
                $body_part_location{$you, "head"} = $pig;
        FMPL:   ask(~pig, be_stuck(ask(.#self, head)))
        FMPL-SFG: pig's be_stuck(.self's head)
        fcl:    if pig is somewhat available
                    then locality(you.head, pig) is very high.
