> Also, you can do `value := myMap[someKey]`, and it will just return a value or nil.

It might if your map is a `map[typeA]*typeB` but it definitely won't return a `nil` if your map is anything like `map[typeA]typeC` (where `typeC` is non-nillable; i.e. int, float, string, bool, rune, byte, time.Time, etc.) - you'll get a compile error: "mismatched types typeC and untyped nil".
