go - Slice as a key in map

Question

Is it possible to use slices as keys?

There is my attempt:

h := map[[]string]string{
  []string{"a", "b"} : "ab",
}

the compiler gives me an error invalid map key type []string. So either it's not possible or I declared it incorrectly (if so, what would be a correct way?).
