    Here’s the abstract:

    Many Scheme systems provide mechanisms for inspecting the arity of a
    procedural value, making it a common feature, however there is no
    standard interface. As a result there is no portable way to observe
    the arity of a procedure without actually applying it. This SRFI
    proposes a simple interface that is consistent with existing Scheme
    systems’ facilities and prior proposals.

    Regards,
