There are many instances of the 'no' function in the source code, but very few instances of the string 'no if'.  See attachment for output of 'ack '\bno\s+if\b' .'.  Almost every instance is testing one of Perl's special variables against some value and, as you say, most are warnings-related.

Unfortunately that isn't getting us any close to solving the problem.  Is anyone familiar with where/how 'no' is implemented in the source code?

Thank you very much.
