Paul King commented on GROOVY-7432:
-----------------------------------
Yes, design of general purpose libraries can be a little hard - I think you
could justify either pattern - if this case ends up being the only one where
you don't re-join into Strings or if you start getting lists of chars instead
of String for the char-args case, then I'd join to Strings but otherwise your
suggestion sounds fine to me. We just have to document clearly. And remember
that the string.toList().groupBy() option isn't far away if they want the other
behavior.
> Enhance CharSequence with appropriate Iterable extension methods

> 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.
