FWIW, I prefer your version, simply because my brain effortlessly translates the else
into $_ != 'ooyah'
, so it is immediately clear to me that the block gets executed if and only if $_ != 'ooyah'
. I think I can understand the prof's desire for the "dangling return", but I also think it would require a few more clock cycles for my brain to look at that and be convinced exactly under which conditions 0 would be returned. (At the very least, I'd have to see the return 1
above to know that the return 0
would never get executed if the if was true -- because the if might just have done some work without actually returning...)
