In new_date_append(), you are assigning a value to $monster_date, which is an undeclared variable, as far as I can see. Why aren't you getting an error message about that? That assigned value uses a global variable named $passed_new-date, which is not passed at all. The new value then becomes the return value of the routine.

$fref is assigned a reference to the subroutine, which might then be invoked as $fref->(); $$fref is meaningless and should generate an error.

As Occam said: Entia non sunt multiplicanda praeter necessitatem.
