I defined the concat function in TS and Python below: https://news.ycombinator.com/item?id=38391702 https://news.ycombinator.com/item?id=38391702 Now, obviously Python doesn't support it due to a restriction in the TypeVarTuple PEP, which is the literal entire point of everything I have written. But what more are you asking for? What more do you want as an example? I am not going to touch the intersection function, as I haven't made any claims in that direction.
