The "generics" feature of Carbon is a large design effort that needs to be broken up into manageable steps. The first thing we need is a high-level goals document:
The question of what a generics feature would look like in Carbon has been an ongoing discussion, with many alternative proposals. Of course there have been a number of use cases that we want to address with this feature, but over the course of this process we have discovered a number of desirable properties we would like to achieve with any solution.
See the generics goals document.
The goals here well reflect Carbon's goals as applied to the specifics of the generics feature.
