Re: [boost] [Boost-interest] C++ library for runtime-concepts (type-erasure)
DEFINE_ERASURE( Calculator, (add)(sub), virtual double add(double) = 0; virtual double sub(double) = 0; )
I would like feedback on how such an implementation would be received by the community.
Hi, I think this macro would not work for the following interface: DEFINE_ERASURE( Dict, (getPair), virtual pair<string, string> getPair() = 0; ) This is because the comma comma 'pair' will be interpreted as separatinh third from the fourth macro param. Regards, &rzej

It works as long as __VA_ARGS__ is only used to do plain text copy, which is the case here: struct Concept { \ __VA_ARGS__ \ }; \ Regards, Ivan
