For a mere mortal like myself, the code isn't that simple :-)

Sure, the lookup is very fast, but how about the indexer function encode()?
    vec( $bits, $_, 2 ) = $acgt{ substr $string . 'a' x 16, $_, 1 }
        for 0 .. 15;

Is it worth the effort looping concatenations through substr()'s and performing hash lookup before vec()torizing into $bits, followed by unpack()ing it? This overhead is less noticeable, right? Just curious.

Note: I made the correction for $bits.
