(I work at Stripe.)

Thanks. I don't think these are so much incorrect assumptions so much as things we should change if the world changes.

19-digit IINs are found on UnionPay, Maestro, and other international cards that Stripe doesn't support today. We might add support for them in the future.

As to the others (e.g. American Express cards with more than 15 digits): we'll certainly add support if this changes.

I took the goal of the library as general purpose, not stripe purpose. Sorry for my personal incorrect assumption.

No problem. The goal is to be general purpose, though, and to that end we just added support for UnionPay, Maestro, and Laser: https://github.com/stripe/jquery.payment/pull/5.

Awesome :)

We'll get UnionPay & Maestro support added shortly.

Is that not the definition of an assumption? Something you rely on being true and not changing, and which if it does change, requires reaction?

These are incorrect assumptions. It's okay to have them, you don't have to be perfect, but don't redefine "assumption" because you're embarrassed.

What is there to be embarrassed about? Seriously.

It's not a redefinition of "assumption" but rather a justification as to why these assumptions should not be qualified as "incorrect".

Gimme a break. The assumptions are correct, for now. If they become incorrect, Stripe will update the software accordingly. This is exactly how good software is written and managed. Patrick has nothing to be embarrassed about.
