As far as I know, no perlmonks article exists covering the problems with prototypes for the simple reason that people always point to Christensen's. But it has been discussed, see When to use Prototypes? or Are prototypes evil?.

As for whether the Camel mislead you, probably not. You probably mislead yourself. Prototypes do exactly what the Camel tells you that they do. Whether you noticed the consequences of the same is another story.
