Are you aware of the trick of "var _ foo.RequiredInterface = myType{}" to make the compiler enforce that a struct implements a given interface?

Is what you seek a nicer syntax for this or does what you speak of bring something more feature wise?

At least IntelliJ IDEs will always make it clear what interfaces all your structs implement.

Yes, and while it uses the compiler to ensure a type implements an interface, it's still a trick that exposes a large hole in the language... and begs for it to be filled. Most importantly, it still doesn't make the code much easier to read and understand.

>At least IntelliJ IDEs will always make it clear (or less foggy)

Indeed. Go benefits hugely from IntelliJ, or to be specific the IJ plugin API.
