#101 closed defect (fixed)

lambda list checking optimizes away dispatch macros which return nil

Reported by: Mark Evenson Owned by: somebody

Parent Tickets:


After [r12693][1], dispatch macros which return nil are stripped from processing in lambda lists.

For example

CL-USER> (defun foo (&key (this :that))

CL-USER> (foo :this (#+:nil :other))
Odd number of keyword arguments.
   [Condition of type PROGRAM-ERROR]

Among other things, this causes [usocket][2] to fail to load, erroring with the slightly mysterious "Unrecognized keyword argument :NAME" as reported by Kevin Raison.
