   'Say no to ampersands unless you know what you're doing.'.

Anyone who can write Eratosthene's Sieve in a one line regex, can be trusted to know what they're doing.

Superficially, this is a question of programming style, far more pedantic than using map in a void context.

In my opinion, prototypes have just as many pit-falls.
I say 'don't use prototypes unless you know what you're doing.'.
If someone else uses protos, read the code and use & wisely if you like.
