+[section consumer_map]
+
+A [consumer_map] groups together multiple consumers, keyed by type they consume.
+When a [ProducerConcept] is connected to a [consumer_map], the consumer
+whose key matches the [ProducerConcept]'s produced type will be chosen for
+the connection.
+[consumer_map] is a wrapper for [BoostFusion] maps which allows them to be
+used in this fashion.
+
+
+A [consumer_map] is used as the return type of [^[storage].send_slot()],
+which and includes the [slot_selector] for both the fused and unfused
+versions of the `send()` function. The appropriate slot is selected when
+a connection is made, based on the [ProducerConcept]'s outgoing signal
+signature.

+To define a new [ProxyProducerConcept] class type, it is sufficient to define
+member typedefs `proxy_producer_category` and `proxy_producer_for`,
+and member function `get_proxied_producer`.
