In particular, you can retain access to the user/interface, and always
just query when probabilities aren't 100%. In general, retain access
to a higher power, such as offering a hook ( def butdonotguess( raw,
guesses ):). If you're making the decision, and a case-by-case is too
expensive, then you've made a policy, and someone gets shaft "'cause
policy". You can throw an exception that's guaranteed to be handled
or exits. '121212' isn't as bad as '121110'! If you want to find out
who and when writes dates like that, apply to PR. Obviously a person
knew at one point what the string was; how much is left?
P.S. def welltheydidthatthistime( raw, guesses ):.
