Several special forms have been introduced to support some of the Scheme Requests for Implementation (SRFI). Note that MIT/GNU Scheme has for some time supported SRFI 23 (error-reporting mechanism) and SRFI 30 (nested multi-line comments), since these SRFIs reflect existing practice rather than introducing new functionality.
