File tools/dom/src/EventStreamProvider.dart (right):

https://codereview.chromium.org/2899173002/diff/1/tools/dom/src/EventStreamPr...
tools/dom/src/EventStreamProvider.dart:239: : _wrapZone<Event, dynamic>((e) =>
(onData as dynamic)(e)) {
Feel free to skip for this CL as it's nothing you're changing.

The "onDart as dynamic" looks a bit dodgy here.  Given the types,

onData(e as T) 

or 

_wrapZone<T, dynamic>

might make more sense.

File tools/dom/templates/html/impl/impl_HTMLSelectElement.darttemplate (right):

tools/dom/templates/html/impl/impl_HTMLSelectElement.darttemplate:13: var
options = this.querySelectorAll<OptionElement>('option');
whoa -  a generic method in the dom!
