the thing to do is to stop fiddling with experimental and potentially
expensive features (like environments), and instead to make "this" a
fluid.

so:

so your evaluation would proceed like this:

scm_c_with_fluid (this_fluid, AS_SMOB (this), call_string_evaluating_method, 
this);

and `call_string_evaluating_method' is defined thusly:

extern "C" void
call_string_evaluating_method (StringEvaluatingClass *obj)
{
   obj->do_string_evaluation ();
}

see also `scm_c_with_fluids' if you want to bind several things this way.

assuming I understood what you wanted,
