   "By calling this function, the garbage collector learns
   about all references that your SMOB has to other SCM values."

   what is "has to other SCM values"? is it a typo?

Perhaps that object contains (points to, references) other
sub-objects.  The SMOB's mark function must call (back to) Guile's
mark function for those sub-objects.  In this way the collector learns.
If the mark function fails to do that, the collector remains ignorant.
