how do I instantiate an iterator in kotlin? every iterator is an interface

That sounds like an XY Problem. What are you trying to achieve?

draw a line between every point in a list of points

that sounds like you always want to process one point with the next

so from it to it.next() presumbaly. i could do like...
`for (point in 0 until points.size -1)` ?

and just use `points[point]` and `points[point+1]` but i figured kotlin has a more elegant solution

^ that.. i knew there was a thing for this, in other cases maybe fold would have been useful too

then use *windowed* (<https://kotlinlang.org/api/latest/jvm/stdlib/kotlin.collections/windowed.html>) with size of *2* and step of *1*

looks like it was deleted? because `CharSequence`?

yep, at first i posted the wrong one of `CharSequence`
