Looks like it's fixed now

The task was OK, but why is the function named Past??

@howardjones: kata fixed just now.

Thank you!

With regard to the incorrect test data, the Haskell sample test has the same incorrect test.

There's a trick to it. But it's based on an old door knocking joke. You just need to do a little "knock knock."

In Python, not only does the sample test call the wrong function (expect vs assert) but the test itself is wrong:
test.assert_equals(justify('123 45 6', 7), '123 45\n6')
123 45 is 6 characters, not 7.

same with the python version... looks like i'ts a guessing game rathen than a programming excercise?

Yes, I don't understand anything regarding this kata.

The (Javascript at least) description cuts off before the end...

On JS version - there is literally one cryptic line of description, and no tests??

In case anyone wants some test numbers which aren't legit, there are standard ones: https://www.paypalobjects.com/en_US/vhelp/paypalmanager_help/credit_card_numbers.htm
