Hi Corion,

MCE requiring a "major" rewrite is a strong phrase. Not all use-cases requires a "major" rewrite. Typically, changes are print to MCE->print or MCE->say. The other having to write an output iterator if wanting to preserve output order which is added code and not so much changing the original code.

MCE::Loop can wrap serial code quite nicely, only changing a few lines.

Serial code.

   my @input = 100..200;

   foreach (@input) {
      print "$_\n";
   };

MCE code.

   use MCE::Loop max_workers => 8, chunk_size => 1;

   my @input = 100..200;

   mce_loop {
      MCE->print("$_\n");
   } @input;

MCE::Map requires only a single line change. Replacing map with mce_map.

   use MCE::Map;
   use Time::HiRes 'sleep';  # for simulating work

   my @a = mce_map { sleep rand; $_ * 1.618 } 1 .. 100;

   print "@a\n";
