We solve the multiple dispatch problem for a \textit{components-for-cases} encoding of algebraic datatypes in C++. For the multi-method, the programmer is required to specify the decentralised match statements using overloads of template functions. Then, they employ a one-liner preprocessor macro, which expands to the real dispatcher. The expanded one-liner performs iterative pointer introspection to accomplish late-binding using overload resolution. Even though we present our solution for ADTs, one can use the same technology for other types too.
