tests/corelib_strong/iterable_skip_test.dart:218: var dynamicSkip0 =
set2.skip(0);
Alternatively, could make the set2 declaration be Set<int>, since it doesn't
look like the type is material.  I'm fine either way.

tests/corelib_strong/sort_test.dart:13: intPairToInt compare = (a, b) =>
a.compareTo(b);
I think you could just write this as

var compare = (int a, int b) => a.compareTo(b)

if preferred.  Either way is fine.
