more PROs:

  - You become less dependent on someone else's library.
  - You learn how to do some things yourself.

;-)

of course, I would prefer a less verbose, and safer version, 
which D enables, such as:

foreach(val; a)
     {
         writeln(val);
         if (val != ';')
         {
             b ~= val;
         }
     }
