Subject: How does && work in ruby

Hi there,

Can someone explain to me how the && operator works (in simple terms -
I'm a Ruby newbie! (That even rhymes! ;-)

More specifically, why does this piece of code assign a user object (or
nil) to @current_user, not true or false?

@current_user = current_user_session && current_user_session.user

Thanks,

Phil
