    * Returns a string representing the specified map. The returned string
    * looks like this: [:'{key0: value0, key1: value1, ... keyN: valueN}':].
    * The value returned by its [toString] method is used to represent each
    * key or value.
    *
    * If the map collection contains a reference to itself, either
    * directly as a key or value, or indirectly through other collections
    * or maps, the contained reference is rendered as [:'{...}':]. This
    * prevents the infinite regress that would otherwise occur. So, for example,
    * calling this method on a map whose sole entry maps the string key 'me'
    * to a reference to the map would return [:'{me: {...}}':].
    *
    * A typical implementation of a map's [toString] method will
    * simply return the results of this method applied to the collection.
