Eric Milles closed GROOVY-11326.
--------------------------------
Resolution: Fixed
I prototyped this out and didn't find enough value for the added complexity.
The {{collect}} changes allowed {{List}} and {{Set}} to come through. A change
to {{collectEntries}} would only effectively expose {{SortedMap}} and
{{NavigableMap}} while at the same time exposing the impl. classes like
{{LinkedHashMap}} and so on.
{{findResults}} could return {{List}} instead of {{Collection}} but that would
prevent any future change that uses a different data structure.
> DGM: improve return type for methods accepting collector

> Extension methods like {{collectEntries}}, {{collectKeys}} and
> {{collectValues}} that accept the collector that is returned can return that
> type. See {{collect(Object,Collection,Closure)}}.
