This issue was originally filed by davidm...@google.com

The most used predicate over a collection is: does it have anything in it?

But the interface provides only "does it have nothing in it", i.e. isEmpty.

This leads to lots of use of !foo.isEmpty, which is confusing as 1) it's a double negative 2) one negation happens before the main expression and the other after.

Suggestions:

 + New method, e.g. hasElements, hasItems
 + Or supplement bool some(bool f(element)) with default some((e) => true)

I think we should have hasElements on Collection. It should be a getter, and so should isEmpty.
