#11995: Deduce key type from return type of key extractor

------------------------------+--------------------------
 The "key extractor" passed to `key_of_value` must specify the key type as
 a nested `type` definition and the `operator()` that extracts the key of a
 `value_type`.

 I think the nested `type` definition is redundant and could be determined
 from the returned type of the key extraction `operator()`.
