Chez Scheme doesn't make this particularly obvious, but it is fairly easy
to do once you realize what it is you are doing.
<http://www.scheme.com/csug8/debug.html#./debug:h4>
There are two means of doing this: the interactive or procedural
inspector. The basic process is the same in both. You inspect the
procedure, and then examine the source. If the source is a procedure, it
will have a lambda, followed by the formals. You can then get the
information you need from examining what the formals structure is.
Building a 'procedure-arity' procedure would be fairly simple on top of
this.
