Hi Alex, I am still working on the idea of using non-tagged pointers in miniPicoLisp - in order to get rid of the requirement that function pointers be word aligned. In the process I noticed that the definition of tail is as follows -
#define tail(x) (((x)-1)->cdr) Does this not result in going outside the 0th cell? Would this be more appropriate? #define tail(x) (((cell *)((long*)(x)-1))->car) Regards, Kashyap
