operator fun <K, V> Map<out K, V>.plus(pair: Pair<K, V>): Map<K, V>(source)

Creates a new read-only map by replacing or adding an entry to this map from a given key-value pair.

The returned map preserves the entry iteration order of the original map. The pair is iterated in the end if it has a unique key.
