Why isn't this change also in the .direct.expect file?

[ahe, 2017/07/14 09:42:26]

It's probably because it already fails today, this is from compile.status:

DeltaBlue: Fail # Missing types on constructor parameters.

The direct.expect file is from dartk, and I need to go through them manually at
some point to ensure that there are no regressions.
