Note that this is also the assumption on the !cached, even if changed to use SCM_UNPACK: SCM cached; if (!SCM_UNPACK (cached)) ... where SCM_UNPACK is defined in /usr/include/libguile/tags.h to be either #define SCM_UNPACK(x) (x) or #define SCM_UNPACK(x) ((x).n.n) In both cases, the check is whether an uninitialized variable is 0...
