so if I type "1", are you going to suggest all possible numbers
that start with that digit?  doesn't strike me as very practical.

maybe you could post a more detailed example, where you clearly
explain what a pattern is and how it is defined, what prediction
means, and what you want to happen as new input arrives, so we
don't have to guess?
