The #golang proposal to introduce generic functions and types (via parametric polymorphism) has been evolving nicely. This https://abs.twimg.com/emoji/v2/... draggable="false" alt="🧵" title="Thread" aria-label="Emoji: Thread"> summarizes what the latest is:

- [] sqr brackets to be used for type param
- type param must have a constraint
- constraint `any` will be new keyword

Use type constraints to define the set of types that can satisfy type arguments

Example: defining and using a generic function

Types can be constrained by behavior by specifying a list of methods that must be implemented by the type argument

Constraints can be more restrictive by specifying both a type list and a method list

Beside functions, types can be defined as being parametric

Example: using a generic type
