Peter Ledbrook commented on GROOVY-7432:
----------------------------------------
These are just a few notes I want to add to the pull request to bring
reviewers' attention to anything I'm uncertain about.
* Will the return type signature on {{groupBy()}} work in a type-checked
environment?
* {{containsAll()}} accepts a {{CharSequence[]}}, which means that objects of
type {{String[]}} need to be converted, otherwise you get a
{{MethodMissingException}}. Does that seem reasonable?
* Should return types, particularly in generics, use {{String}} instead of
{{CharSequence}} since strings are invariably returned from those methods?
> 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.
