* 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 |
* their parameters are valid and no other error occurs." |
