Ah - only that I wasn't familiar with GOOPS.
How about these snarfing macros, though?
* snarf.h (SCM_SMOB, SCM_GLOBAL_SMOB, SCM_SMOB_MARK,
SCM_GLOBAL_SMOB_MARK, SCM_SMOB_FREE, SCM_GLOBAL_SMOB_FREE,
SCM_SMOB_PRINT, SCM_GLOBAL_SMOB_PRINT, SCM_SMOB_EQUALP,
SCM_GLOBAL_SMOB_EQUALP, SCM_SMOB_APPLY,
SCM_GLOBAL_SMOB_APPLY): New macros.
