Zip

Basics

Name: Zip

Type: list<tuple<varies, varies>>

"Zip" together two lists of the same type (similar to python's zip method). If the optional truncate is true (defaults to false), the result's length is the minimum of the two. Otherwise, the two lists have to be the same length.

The return value would a list of tuples, each tuple holding 2 values, one from each list.

Unless truncate is set to true, Zip will fail if the two lists are not the same lengths.
