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.

SRFI Editor
