time.Second*1 gets the same value; it's not overloaded. Well, ok, so what actually happens is that time.Second is a time.Duration, and Duration*int yields Dura

time.Second*1 gets the same value; it's not overloaded. Well, ok, so what actually happens is that time.Second is a time.Duration, and Duration*int yields Duration (and int*Duration yields Duration). But the value of time.Second is actually a Duration with value 1000000, IIRC -- it's microseconds. It's just the type that's special, and the int handling here is general over a lot of types. It really is nice in practice.
