Add a missing T

Adds a missing T.

Wait, this is potentially binary breaking, is it not? 🤔

[LukaJCB]

Yeah seems, like it. I'm gonna file this one for 2.0 :)

[mcanlas]

Just driving by. @LukaJCB Is there a resource/document that outlines which changes an author could make that are binary breaking and which are not? And isn't there a tool that helps with this also?

[kailuowang]

Yeah it's BC breaking.

[andyscott]

Indeed!

[LukaJCB]

@mcanlas Check out mima, it's the tool we use and it also describes what's binary breaking :)

[kailuowang]

@mcanlas rule of thumbs is that

1. you can't change any existing public members.
2. you can't add a new method to a trait even if you give it a default implementation.

@andyscott if we really care about this name we could simply change the existing to explicit and add a new implicit one with the correct name, although I am not sure if that's better than a miss-spell.

@LukaJCB this would be BC breaking on scala 2.12 as well. For 2.0 we still want 2.12 BC right?
