The Quality in-house Perl packages item is related to groups in our organization that are tasked with providing Perl packages for existing in-house libraries. Most of them are very familiar with C/C++ and have used Perl for simple things.
They get wrapped around the axle when converting C/C++ apis that follow the memory allocation axiom:
He who allocates memory shall deallocate memory.
For those that have had this axiom burned into their brain, it is very difficult to pass back a reference to something in any language that they have created in the function.
We fear change. --Garth
