2To do what? Create an interface definition that, even though the designers could have specified to be covariant on tv, they didn't?Robert Harvey– Robert Harvey2016-04-03 05:12:07 +00:00Commented Apr 3, 2016 at 5:12

@RobertHarvey I think that's my confusion? I fail to see what the design incentive is to not make the parent class covariant on Tv, here or ever.concat– concat2016-04-03 05:30:54 +00:00Commented Apr 3, 2016 at 5:30

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. design-patterns), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
