It might fail to expand due to a form having no setf expansion being used as a place. The placelet1 macro could be easily refined to detect the situation, and provide an accurate diagnostic. Why I would consider the approach is that it's very simple and doesn't rely on any non-portable features. At least it's worth noting/documenting: "if we are able to take a certain requirement off the table, such and such highly simplified trick is possible which handles the remaining requirements". -- TXR Programming Lanuage: http://nongnu.org/txr Music DIY Mailing List: http://www.kylheku.com/diy ADA MP-1 Mailing List: http://www.kylheku.com/mp1
