Hmm? That actually does seem to work: I get
ben ~ 507 $ ./hashtest.pl
Alabama
Alaska
ben ~ 508 $
(I've called this script "hashtest.pl".)
Were you expecting some other thing to be output?
The version of perl is as follows:
ben ~ 508 $ perl --version
This is perl, v5.8.8 built for i486-linux-gnu-thread-multi
