Agree & Voted. Another alternative that I would like is to have angle brackets < > for better readability, so that definition and call would look as follows: // 1 func Print2<type T1, T2>(s1 []T1, s2 []T2) { ... } Print2<int,int>( ... ) // 2 var v Vector<int> // 3 func (v *Vector<Element>) Push(x Element) { *v = append(*v, x) } Sorry, if it gives you C++ nightmares.
