[frewsxcv]

Should I cherry pick #249?

[frewsxcv]

Cherry-picked.

[frewsxcv]

Looks like there's still an issue (fewer issues though). I don't have time to look into it right now. People can push to this branch if they want to try fixing it though.

gw> emiliocobos: your wr/traits PRs all look fine to me, but there appear to be some CI / dependency issues preventing stuff landing there at the moment. Will look into that today or when back from PTO if no-one else does
emiliocobos> gw: If they look fine, frewsxcv should have just cherrypicked the last dependency problem (#249 and #250 should have passed but we had the appveyor hook configured but not running)
gw> emiliocobos: ok, cool
