in reply to List-to-Range generation

10 years later this is still really cool. I've been using if for a while now and there is one small issue I've seen. If you have a list of numbers, say 1,2,3 ... 39999,40000 and run it through num2range, you'll get the following back: "1-32768,32769-40000" instead of "1-40000".

I'm guessing this is because you can't have more than 32k captures in a regex?

    Hmm, just trying to figure out a way to test this is bending my mind. So is this true? This method only works for ranges up to 2^15?

    What if you split up the ranges? It would work for any list of up to 32,768 consecutive numbers, right?
