The original post came from someone being lazy, that appears to be influencing my take on the thread :) Also given the above code, it's completely pointless since the first operand is true and so it is impossible for return( 'foo' ) to ever be evaluated (and as stated in a post just before this the expression shouldn't break). Nonetheless given a variable as the first operand, I think anyone coding a return in a conditional like that is asking for trouble since I would guess that it has an undefined return value.
