Sorry if I am a bit slow and ask for clarifications. Would this work as follow?

a) If NO_VARIADIC, PP_TUPLE_TO_SEQ always requires 2 arguments for
both the size and the tuple -- as in PP_TUPLE_TO_SEQ(size, (...)).

b) If VARIADIC instead, the same PP_TUPLE_TO_SEQ macro can either
accept 1 argument for the tuple -- as in PP_TUPLE_TO_SEQ((...)) -- or
accept 2 arguments for both the size and the tuple as in a).

Is this correct? Thanks a lot!
