Iterators

An iterator connects to a variable assigned to a list or string and is able to cycle thru its elements/characters.

Eg: 3┅ẇ defines variable w initializing it with list [1,2,3]

Using iterator ẉ we are able to iterate thru the list

Eg: '3┅ẇ 5{ẉ,}R' outputs 1 2 3 1 2

To apply an iterator only variables wyz can be used.

Notice that w still has the entire list, so w, outputs [1,2,3]
