set_error is an error completion function ([exec.async.ops]).
Its associated completion tag is set_error_t.
The expression set_error(rcvr, err) for some subexpressions rcvr and err is ill-formed if rcvr is an lvalue or an rvalue of const type.
Otherwise, it is expression-equivalent toMANDATE-NOTHROW(rcvr.set_error(err)).
