In the case of SEQ_TAIL, it has to go through the non-unary element to tell where the end is which should result in the wrong number of arguments (2) to a macro (which takes 1).
Sorry, I was thinking of extracting the last element. SEQ_TAIL happens to work here because it doesn't need to access (in any way) the tail of the sequence. This is not guaranteed by the library, and the implementation detail should not be exploited. Regards, Paul Mensonides
