According to its documentation, executeShell() returns a Tuple 
consisting of the return status and the output of the executed program:

   http://dlang.org/library/std/process/executeShell.html

Do not print the entire returned Tuple. Instead, print just the .status 
member of it:

     auto result = executeShell(a);

     if (result.status == 0) {
         // It worked! Now we can get the output:

         auto output = result.output;

         // Use 'output' here...
     }

So, 'output' above is what you should pass to extractSerial() function 
that H. S. Teoh has written:

     assert(extractSerial(output) == "92716002xxxx");

(I have not tested the code above.)
