 //   function on the path

-// Notes:
-//
-// FIXME -- we need to evaluate the argument list to determine the
-// dispatch type.  The method used here works (pass in the args, pass
-// out the evaluated args and a flag saying whether the evaluation was
-// needed), but it seems a bit inelegant.  We do need to save the
-// evaluated args in some way to avoid evaluating them multiple times.
-//  Maybe evaluated args could be attached to the tree_argument_list
-// object?  Then the argument list could be evaluated outside of this
-// function and we could elimnate the arg_names, evaluated_args, and
-// args_evaluated arguments.  We would still want to avoid computing
-// the dispatch type unless it is needed, so the args should be passed
-// rather than the dispatch type.  But the arguments will need to be
-// evaluated no matter what, so evaluating them beforehand should be
-// OK.  If the evaluated arguments are attached to args, then we would
-// need to determine the appropriate place(s) to clear them (for
-// example, before returning from tree_index_expression::rvalue).
