that's what I was worried about. then below: wont
  expect(_, isElement)
always pass? even if I pass something of the wrong type?

For instance,
   expect(new Foo(), isElement) // would pass
when:
   expect(new Foo() is Element, isTrue) // fails?

[gram, 2012/10/26 22:26:27]

Yes, for now, these will always pass in dart2js. I didn't realize that these
would work correctly in the non-templated version, but it seems they do. So I
will have to undo all the type tests. I am going to leave the new versions in
but commented out so that when the time comes we can easily clean this up.

+  // of arguments these don't work if they use isNot. For now those are
+  // written in a different way but should ultimately be replaced by the
+  // commented-out versions. These have been marked with //* to distinguish
+  // from tests that were already commented out.
