why?

[Mads Ager (google), 2013/03/19 12:40:50]

Because Uint8ClampedList inherits from Uint8List in typeddata I believe.

[Anton Muhin, 2013/03/19 13:22:34]

It doesn't in sdk/lib/typeddata_base.dart nor in vm's variant.  Apparently.

That is true. Hmm, maybe it never did? I was sure I saw that somewhere. Sorry
for the noise.

Sorry, this file was an accidental inclusion.  I'm still looking into why this
test fails.  This was one of the things I hit.  In JS, Uint8ClampedArray
inherits from Uint8Array.  In Dart2JS today, it's hard to not have that
behavior, but Stephen thinks it'll be straightforward when interceptors become
more pervasive.
