<lang Dyalect>for i in [1,2,3] {

print(i)

}</lang>

This code would work for any type that has a method "iter" (which returns an iterator). In fact a runtime environment silently call this method for you and creates an iterator out of an array. The code above is absolutely identical to:

<lang Dyalect>for i in [1,2,3].iter() {

print(i)

}</lang>

This would perfectly work with any custom iterator as well:

<lang Dyalect>

func myCollection() {

yield 1

yield 2

yield 3

}

for i in myCollection() {

print(i)

}</lang>

All three code samples would output:

<pre>1

2

3</pre>
