Any chance we could get a flavour of the code? A desensitised sample perhaps.

If not did it use strict and warnings? Did any other CPAN modules make the grade? Is it OO or procedural, Moose or Modern?

Which version? Was it a standard interpreter or embedded or otherwise heaviliy customised?

How many lines of code? What testing regime do you use? Basically anything that gives us a feel for the way perl was used.
