| * a command, that command has no effect. This is somewhat |
| * unfortunate for multi-bind commands, because it would require |
| * a first pass to scan the entire list of bound objects for |
| * errors and then a second pass to actually perform the |
| * bindings. Should we have different error semantics? |
| * |
| * RESOLVED: Yes. In this specification, when the parameters for |
| * one of the <count> binding points are invalid, that binding |
| * point is not updated and an error will be generated. However, |
| * other binding points in the same command will be updated if |
