let return value's type to be an interface

[springeye]

An interesting idea. But I'm not sure if it's feasible, because I think it would be difficult to identify at the syntax tree level which structs implement which interfaces. Does anyone else have any thoughts on implementation?

"I also really need this feature because I want to use it with Wire. I think it would be great to add a parameter to specify the interface to bind, just like Wire does, for example: newc -i=Doer."
