Re: [FWP] Sideways Perl

["Edward M. Perry" <eperry@learjet.com>]

sideways perl should augment the very useful swap perl nicely.

swap perl:
----------------------------------------
#!/usr/bin/perl
use strict;
my (@l, @m, $i);

while (<>) {
   chomp;
   @l = split('');

   for ($i = 0; $i < @l; $i+=2) {
      ($l[$i], $l[$i+1]) = ($l[$i+1], $l[$i]);
   }

   push (@m, join('', @l));
}

eval join ("\n", @m);
----------------------------------------

swap perl sample:
----------------------------------------
su etsirtc;
ym( l@ ,m@ ,i$;)

hwli e<()>{
  c ohpm;
  @  l =psil(t'';)

  f ro( i$= 0  ;i$< @ ;l$ +i2= ){
      $([li$,]$ [li$1+)]= ( l$$[+i]1 ,l$$[]i;)
  }

  p su h@(,mj io(n'' ,l@));
}

velaj io n"(n\,"@ )m;
----------------------------------------
