As for correctness, did you try running mine? Yours gives only five results on my dictionary as well. If mine isn't capturing everything, I can't figure out why. Help?

As for the differing results we got, note that I included the version of /usr/share/dict/words that I used; mine, for some wacky reason, doesn't contain the words 'yam', 'mom' or 'tom'. It does contain 'Tom', (not 'Mom' or 'Yam') but I was looking for improper nouns. Good catch on the case issue, though I notice your example has it as well. Eh, it's not a hard fix.

The bit about using hashes is quite nifty. I was considering breaking it down to one pass, but couldn't figure out how to get it to be order-agnostic. (I was still using a single pointer in the list.) The hash neatly sidesteps all of that. Cool!

I should learn to use non-capturing parentheses when I'm not snagging the output, too.

Thanks!
