Re: [boost] [bimap]

bimap<X,Y> bm; bm.left // --> map<X,Y> : X first, Y second bm.right // --> map<Y,X> : Y first, X second

You may want to consider the nomenclature "forward" and "reverse" - for directories, this is the standard way of referring to, for example, look-up of a telephone number from a name and look-up of a name from a telephone number, respectively. Reverse also indicates that the order of the template arguments are reversed in that case relative to the order in which they are declared. Matthias
