Title: mutable.MapLike: override $mapNote to reflect actual require mutable api

The api needed to define a mutable.Map is different then the one
needed to define an immutable.Map. Prior to this patch the mutable one
reflected the api needed for the immutable one causing confusion about
what really needed to be defined.
