//=============================================================================
// MEMBER FUNCTION SPECIALIZATIONS
//=============================================================================

// Specialization for T == bool:

//$$SCRIBBLE: This specialization requires that all lower
//            case is used in xlist; eg: "true false" as
//            opposed to  "TRUE FALSE"". This limitation
//            could be eliminated with a "bool to_bool(string)"
//            function.
