It is a dream that Scheme have such a feature, but it really requires threads to maximize their usefulness so I’m not sure which RnRS we’re talking about.  Perhaps it is time to think about adding SRFI 18 to Scheme… it has seen close to 20 years of experience in the field and is supported by many implementations of Scheme.
