swampyankee has asked for the wisdom of the Perl Monks concerning the following question:
I'm looking for some hints on how to write a module which adds new (and largely superfluous) operators to Perl, specifically to replicate Fortran's .EQV. and .NEQV. logical operators. I won't argue that these are useful additions to Perl–I've programmed Fortran for close to forty years and never used either–but it does seem like a fun little project.
