I agree that BioPerl would significantly increase in value with
such a module; in fact, the BioTeam would probably buy us out.
My opinion is that the entire GWAS enterprise is the search for
such a callback function, for humans anyway. For those engaged
in this quest, if BioPerl doesn't provide a Maserati, it at least provides
good italian-made (among others) parts.
