Subject: Re: puts and return

Interesting. Thanks.

One sees control code like this in rails all the time:

redirect_to <somewhere> and return if <condition>

Never having looked at the return value from redirect_to (but guessing 
it's always non-nil), I guess I assumed 'and' was the non-short-circuit 
operator.

Otherwise, why this is idiom so prevalent?  Because it looks more 
English-like?
