2 way std::map

[bb]

Hi,

Currently, am achieving 2 way mapping as follows:

typedef std::map<std::string, std::string> MapOfStrings;

MapOfStrings m1;
MapOfStrings m2;

Populating m1 & again m2 in reverse.

Is there a better way to do this using a single container?
Is there any 2 way 'map' from open source (e.g. boost) available?

Thanks.

See this thread; it's about pretty much the same thing:
