I agree that when possible, matchers should be available via the dynamic matchers API. It doesn't seem overly complicated to add this support here. As far as I understand, we just need to register the matcher in lib/ASTMatchers/Dynamic/Registry.cpp and add support for `CastKind` argument type (by adding a corresponding `ArgTypeTraits` instantiation). Etienne, can you try this?
