What did you do?

$ go doc math/rand Seed | tail

The last paragraph reads

Programs that need a specific result sequence should use NewRand(NewSource(seed)) to obtain a random generator that other packages cannot access.

The constructor for rand.Rand is called New, not NewRand, so it should say "should use New(NewSource(seed))".
