  56    in some versions of guile, it is actually a typedef to "void *".
  57    That means that in C++, an explicit cast is necessary to convert
  58    function pointer to scm_t_subr.  But a cast also makes it possible
  59    to pass function pointers with the wrong type by mistake.  So
  60    instead of adding such casts throughout, we use 'as_a_scm_t_subr'

  62    pointer types that are valid.
