> Password validation is a degenerate case of parsing

Really? How is that degenerate? Compared to what?

My guess is that you just decided to use a dictionary word you don't fully understand.

> In fact you could use an invalid password

Where does this nonsense come from? No. I cannot use invalid password. That's the whole point of validation: making sure it doesn't happen. What kind of bs is this?

> But that doesn't mean that `string -> Password` isn't parsing!

It's doing nothing useful, and that's the whole point. You just patted yourself on the head in front of the mirror for using some programming technique that you believe makes you special, but accomplished nothing of value. That was the original point: if you want results, you will end up doing validation, there's no way around it. You renaming of types is only interesting to you and a group of people who are interested in types, but doesn't advance the cause of someone who wants their password validated.
