[Bob Nystrom, 2016/03/28 21:05:37]

Shouldn't this be DYNAMIC_CAST now? Did I do something wrong in the error
generation?

[Leaf, 2016/03/28 21:09:09]

I don't think so.  E is potentially a composite type, so I think we treat this
as a down cast composite.

[Leaf, 2016/03/28 20:24:49]

Did something happen to dart:html in this roll?  It looks like all of the error
messages went away, which seems suspicious... :)

[Jennifer Messerly, 2016/03/28 21:22:08]

funny that. So what happens, is apparently we now run some node.js tests, and
they overwrite(!) our SDK error log. I usually kill the presubmit before they
get there, because I didn't know that step was lurking at the end, after the
format :)

anyway would be good to fix, maybe I can restore this in a follow up CL
