Description

We should add helper methods to Number to support this

for (i in 10.step(1, 2))

{ ... }


(i.e. provide one which doesn't take a closure and returns an iterator instead).


Also we should offer a step() feature on ranges so we can do things like

for (i in (10..1).step(2)) { ... }

or

(10..1).step(2)

{ ... }
