|go ahead... be a heretic|
and how you eventually used the it like so:
".. But as far as the prototype passing, I was certain that it enforces a pass by reference..."
If I may suggest, you will do well yielding the wisdom of jwkrahn, as regard the usage of prototype for this reason:
When you use a reference prototype, like "\$", "\@", "\%" "...those symbols don't actually say that you must pass in a scalar reference, an array reference, and a hash reference. Rather, they say you must pass in a scalar variable, an array variable, and a hash variable. That means that the compiler insists upon seeing a properly notated variable of the given type, complete with "$", "@", or "%" in that slot. You must not use a backslash. The compiler silently supplies the backslash for you... "

Hope this helps.
If you tell me, I'll forget.
If you show me, I'll remember.
if you involve me, I'll understand.
