Now let's open the case for the prosecution. Let's assume that we have a
persistent whiney developer who is determined to use prototypes on every
Perl subroutine and is attempting to defend his choice:

1. Prototypes allow Perl to pick up errors in subroutine calls.

This is a common mistake made by developers who have a background with 'C',
since this is exactly what 'C' prototypes are for. *It is unfortunate that
Perl uses the name 'prototype', since in Perl, the feature exists for an
entirely different reason - to allow Perl to silently coerce the arguments
into a form that matches the prototype. In fact Perl's compiler will only
throw errors if it can't manage to do that.*

Exatamente o que eu pensei enquanto lia. Péssima escolha de nome, não
deveriam ter chamado de protótipos. Aliás, realmente, tirando o syntax sugar
eventual, RUN FORREST, RUUUN!
