master and newast both have issues with 1.9
[NativeException] exception expected, not
errors should be easy, because they reflect an API change.
assertion message must be String or Proc, but Fixnum was given.
@ test/core/ast_test.rb:351:in `test_return'
update: above is a bug where we use assert instead of assert_equal
also newast uses each_with_index on strings in a few places, and that causes errors.
There's also these problems:
ERROR (0:00:14.249) test_unquote_method_definitions_with_main
argument type mismatch
so those are probably ok.
I think we've got all these.
