Write a program which performs brute force letter combination until the word "password" is found
Perl, 19 chars

say for a..password


Uses newlines as delimiters, per clarification above.  Run with perl -M5.010 (or just perl -E 'say for a..password') to enable the Perl 5.10+ say feature.  Per meta, this doesn't count as extra chars.

(If you insist on spaces as delimiters, $,=$";say a..password is only two chars longer.  However, it's also very slow and wasteful of memory, to the point of being unusable in practice, since it tries to build the entire list in memory before printing it.)
