Represents an immutable, ordered sequence of key-value pairs with textual keys. Mapping additionally holds a lazy
initialized map which allows fast lookup by key. When looking up values by key, duplicate entries are dropped and
only the last value for given key is returned.
Mappings have O(1) prepend, append and concatenation operations.
