Hi Bill,
In Radium, all external functions are created with
"s7_define_unsafe_typed_function". Most of the functions could
probably be created with "s7_define_safe_typed_function" instead, but
since many of the functions calls s7_eval I just use unsafe
everywhere, for simplicity. However, none of the functions modifies
the arg list. I think this would be a common situation. Perhaps it
would make sense to create "s7_define_unsafe_stack_safe_args*"
functions in s7?
