8	There are actually more than four examples that it needs to work on. And
9	more to the point, this is going to destroy any other numbers it finds
10	in the input. Phone numbers, zip codes, addresses, credit cards numbers,
11	timestamps, etc. will all get clobbered. It takes like 10 lines of
12	python to do this right; it's silly to invest a ton of effort trying to
13	come up with a regex solution that accidentally works.
