Dickens also rates an 8

by Jerrad Pierce

It's a little known fact that before he took over operations at the North Pole Santa was working on his M.B.A. As jolly as the old elf is, he's a real stickler for standards and metrics. Needless to say, the Winter Solstice B&E cookie muncher was thrilled when Test::Perl::Critic was covered but that was sometime ago and he's beginning to long for something more… enter B::Fathom. Fathom gathers some arcane statistics it employs in seemingly arbitrary calculations to generate a value from 0 .. 10 or null to line noise.While the subroutine count seems off, the overall results are not unreasonable as indicated below.
