Map elements are not addressable. Therefore, the following is an _illegal_ operation:
```go
-lists := map[string]List
+lists := map[string]List{}
lists["primes"].Append(7) // cannot be rewritten as (&lists["primes"]).Append(7)
```
However, the following is still valid (and is the far more common case):
```go
-lists := map[string]*List
+lists := map[string]*List{}
lists["primes"] = new(List)
lists["primes"].Append(7)
count := lists["primes"].Len() // can be rewritten as (*lists["primes"]).Len()
