11996	Deduce key type from return type of key extractor	fdegros@…	Ion Gaztañaga	"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()`."	Feature Requests	closed	To Be Determined	intrusive	Boost 1.60.0	Optimization	wontfix
