I'm not sure if it is a bug or not, or if --$# is the problem. I had some folks try:

perl -le 'print --$#';

on 5.6, and they got -1, which is correct. I need a tuit to look into this.

Those who seemed to have an error from this, please try that one line, and let me know if you had an error (with the error), or if you do not.

Cheers,
KM
