I didn't see a definition of score anywhere so I am not sure I've
deduced it correctly other fwpers posts - these two can't both be
correct since they give different answers on some inputs. =)

But at 48 and 51 characters each, they're too nice to keep hidden for
something as trivial as merely being wrong ;-)

perl -e'$/=0;$_=<STDIN>;print eval"tr/$ARGV[0]\n//c"' as <test
perl -e'$/=0;print0+grep/[^$ARGV[0]\n]/,split"",<STDIN>' as <test
