Sadly thats only half of the truth. Many builtins can't be modelled with prototypes and rely on magicly hidden parsing rules.

So prototypes are only a crippled mechanism.

The fact that you can restrict to scalarrefs of $variables with \$ but not to refs of literals is an obvious gap in the definition, which you can't deny.

The possibility to warn about errors like in join @a,@b could make perl much more user friendly.

I don't even see a possibility to warn about this at runtime!!!

(well except magic things like using caller to parse the calling the line of code)
