The point was to make the variable names mean something 
in the context they are used. If you get a fragement like

    for my $g ( keys %phntyp )

You are less likely to guess/remember that it means 

    for my $gene ( keys %phenotype_map )

Using "%authorz" would probalby be sufficient for most
uses, that or you could try %authors_of_books_by_title...

At some point context and <gasp!> comments are necessary
for getting the stuff done.
