You are right, I should have said "Perl prototyping does not always care about the type of the arguments". And that is arguably even worse.

In any case, it only happens when you do "reference prototyping" and the OP did not ask about that dark corner.

A program should be light and agile, its subroutines connected like a string of pearls. The spirit and intent of the program should be retained throughout. There should be neither too little or too much, neither needless loops nor useless variables, neither lack of structure nor overwhelming rigidity." - The Tao of Programming, 4.1 - Geoffrey James
