Colt code is inconsistent in dealing with the following case: iIntSomethingHashMap.keyOf(someValue)
Some code we got from them returns 0 if there is no such value, other code returns MIN_VALUE. In floating-point land, it returns NAN. Personally, I'd be inclined to nuke the entire API. It's implemented as the obvious iteration, and the caller can iterate for themselves without creating a shoot-yourself opportunity for the unwary. Another alternative is to make the signature keyType keyOf(valueType value, boolean[] present) I'm in favor of removal, but I could live with the boolean. Thoughts?
