dagger.gen issues using interface returning a non core type

[polar egret]

Defining an interface which returns a non Dagger core type as for example bool, causes the code generation to fail:

./dagger.gen.go:161:21: too many return values                have (bool, nil)                                      want (bool)                                   
./dagger.gen.go:166:19: too many return values
        have (bool, error)
        want (bool)                        
./dagger.gen.go:166:29: undefined: ctx

👋 in Go, interface functions that return a scalar, should receive a context as an argument and also return an error. You're already doing this in the Foo function. You have to do the same for HasBar

@bronze hedge so in Go boolis a scalar? The same error occurs, if I switch the return type to string.

@polar egret both string and bool are scalars

if you use scalars, you need to add acontext.Context argument and return error to the interface function

the same way you did it for the Foo function
