Description
(This was reported by Joo ChurlSoo?)
Restoring the old value after execution of the body of a parameterize form will reinvoke the guard, which is incorrent, if it performs a conversion (for example number->string).

Possibly fixed. Parameter procedures now accept an optional 2nd argument that will skip the guard procedure, if it is true. This should also work for parameter-like procedures that do not explicitly check the argument count (and should be the case for all parameter-like procedures defined in the core libraries).
