Re: The evolution of a solution to the 11/23 NPR puzzler.

[benizi]

Since nobody's posted a one-liner yet:

perl -lne '$_=lc; next if $d{$_}++; next unless s/(?:m|rn)$//; print "${_}m / ${_}rn" if $h{$_}++' /usr/share/dict/words

Doesn't quite handle capitalization correctly. e.g. "bim / barn", where bim is only in as "Bim".

And even though all these solutions print pairs of words... I don't see the answer. (benizi guesses he'll be kicking himself later for admitting that)

Update: ++halley. (Never having heard the expression, benizi refrains from kicking himself.)
