This actually seems to be slightly quicker than the grep based solution:
Benchmark: timing 100000 iterations of broquaint, grep_seen, aristotle
broquaint: 25 wallclock secs (21.62 usr + 0.01 sys = 21.63 CPU) @ 46
grep_seen: 12 wallclock secs (11.55 usr + 0.00 sys = 11.55 CPU) @ 86
aristotle: 10 wallclock secs ( 9.05 usr + 0.00 sys = 9.05 CPU) @ 11
juerd: 9 wallclock secs ( 8.66 usr + 0.00 sys = 8.66 CPU) @ 11

Always code as if the guy who ends up maintaining your code
will be a violent psychopath who knows where you live.
