Detached transformed collections

[GoogleCodeExporter]

Could you please introduce methods in Lists, Sets, Collections2 (maybe Maps) 
producing detached transformed collections, unlike it is with current 
Lists.transform(), Sets.transform(), Collections2.transform() producing 
transformed views.

These methods (existing and new ones) can take Iterable as an input.

Thanks, Filip

Is this necessary?

In the Javadocs for Lists.transform() it says "To avoid lazy evaluation when 
the returned list doesn't need to be a view, copy the returned list into a new 
list of your choosing.". I'd say that's standard procedure.

Just pass  the transformed collection to one of the collection factory methods 
like Lists.newArrayList(Iterable<T>) or pass it to the constructor like new 
ArrayList<T>(Collection<T>) etc.
