And I second the idea of not using a return code to signify what failed; I do however condone letting undef indicate that there is an error (that can be inspected some other, appropriate, way) if there's no potential for undef as a valid data return.

    Uh, undef is a return code. I don't think that's any better than saying "79" indicates a failure.

      I said:

      a return code to signify what failed;

      (emphasis added).

      I fully realise that undef is a return code. It does not, however, carry information about what failed and why. The lack of defined return code is my signal to go off and look at my object/class and get the error.

      That works for me (and as bryan notes above, is somewhat common in CPAN modules).

      Your mileage might vary, as they say ;-)


      mmm, 69 == success.
