Thanks.

I don't understand what is going on here:


    for idx := range funcs {
            ft := funcs[idx].Func.Type().common()
            ft.uncommon()

            ifn := funcs[idx].Func
            methods = append(methods, method{
                name: resolveReflectName(newName(funcs[idx].Name, "", true)),
                mtyp: resolveReflectType(ft),
                ifn:  resolveReflectText(unsafe.Pointer(&ifn)),
                tfn:  resolveReflectText(unsafe.Pointer(&ifn)),
            })
        }

It looks like ifn will be type reflect.Value.  But you are setting ifn
to the address of that Value.  That doesn't make sense to me.  ifn and
tfn need to refer to executable code.
