This proposal makes sense to me. Disclaimer: I don't know enough about language design to provide feedback on how it may be refined. This is just my perspective as a potential future user.
1. It is one of the simplest proposals I've read so far (but I have not read them all - there are too many to keep up with) 2. It is easy to understand and visualise where it would be used 3. It is orthogonal - it does not tread on the capabilities of other keywords, but complements them nicely 4. In conjunction with the "gen eq" and "gen num" keywords, it would be sufficient for all the work I've needed to do On Friday, May 31, 2019 at 4:29:03 AM UTC+12, Michal Strba wrote: > > Hi Gophers! :) > > I've been thinking about generics in Go 2 ever since the original > contracts proposal and few days ago, ideas finally clicked.
