Paul King commented on GROOVY-7432:
-----------------------------------
We probably need something like:
{code}
private static final class StringIterable implements Iterable<String> {
private final CharSequence delegate;
public StringIterable(CharSequence delegate) {
this.delegate = delegate;
}
@Override
public Iterator<String> iterator() {
return new StringIterator(delegate);
}
}
{code}
And ditto for CharacterIterable:
{code}
private static final class CharacterIterable implements Iterable<Character>
{
private final CharSequence delegate;
public CharacterIterable(CharSequence delegate) {
this.delegate = delegate;
}
@Override
public Iterator<Character> iterator() {
return new CharacterIterator(delegate);
}
}
{code}
Let me know if you want me to add them separate to your PR.

> Groovy enables developers to treat {{CharSequence}}s as if they were true
> sequences. For example, you can use a for loop and the array index operator.
> Some extension methods are missing though. One I was hoping to find was the
> {{count(Closure)}} method. I think it makes sense to incorporate any
> {{Iterable}} extension methods into {{CharSequence}} as well.
