Description
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().
Note:
See TracTickets
for help on using tickets.
The library needs to support C++03, and relaying on a result_of emulation would be overkill.
