This binding is convenient because existing call sites often refer to Univ_map.Key.create.

keys with associated default values, so that find is no longer partial

module With_fold : sig ... end

keys that map to an accumulator value with an associated fold operation

module Multi : sig ... end

list-accumulating keys with a default value of the empty list
