Module Univ_map

module Univ_map: sig .. end

Universal/heterogeneous maps.

These maps are useful for storing values of arbitrary type in a single map. In order to recover a value, it must be looked up with exactly the Key.t it was stored in. In other words, given different Key.t's from the same string, one will not be able to recover the key stored in the other one.

This is similar to Univ in spirit.

module With_default: sig .. end

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
