issue with repeated - Githubissues

Hi ,

I've tried your mock with a repeated field:

    syntax = "proto3";

    package carvalhorr.greeter;

    option go_package = ".;greeter_service";

    service Greeter {
        rpc Hello(Request) returns (Response) {}
    }

    message Request {
        string name = 1;

        repeated ABC abc = 2;
        message ABC {
        string key = 1;
        }

    }

    message Response {
        string greeting = 1;
    }

But I get the following error:

    panic: runtime error: comparing uncomparable type []interface {}
