?! Why doesn't it just return another (compound) Case object and leave the Sequence an unspecified implementation detail...
So you want switch_ to be template<class R, class I, class Cases> requires Case<Cases> && BuiltInIntegerOrEnum<I> R switch(I i, Cases cases); IMO, There is a very big problem here. Suppose that you have a fusion sequence that holds your cases and function objects coming from somewhere else. The problem of adapting it to switch_ is no easier than it would be with my original interface. In Christ, Steven Watanabe
