in thread Golf challange: match U.S. State names

Your subroutine will accept "AK\n" as a state. Fixing that takes it to 125. But I can beat that with the following 122 character solution (which is what I was trying to figure out when I posted my first):
sub state{ $_[0]=~/^\w\w\z/&&grep/$_[0]/,'WVTNHINMSCORIDCAKSDE WIALAR MNCTX NVAZ' +,'FLGAILKTKYMAMDMEMIMOMTNDNENJNYOHOKPAUTWAWY'=~/../g }
OTOH I can improve your idea down to 119:
sub state { pop=~/^([CGILPVW]A|[CKUV]T|[HRW]I|A[KLRZ]|CO|DC|DE|FL|I[DLN]|KS|KY|M[A +DEINOST]|N[CDEHJMVY]|O[HKR]|SC|SD|TN|TX|WV|WY)\z/ }

    Your first one can go down to 121:
    sub state{ grep$_[0]eq$_,'WVTNHINMSCORIDCAKSDE WIALAR MNCTX NVAZ'=~/(?=(\w\w))/ +g,'FLGAILKTKYMAMDMEMIMOMTNDNENJNYOHOKPAUTWAWY'=~/../g }
    ... or you could have just taken the easy route by converting the && into an &.
