The basic facts of macro expansion have counterintuitive consequences. This section describes some important consequences that can lead to trouble, and rules to follow to avoid trouble.
| 13.6.1 Wrong Time | Do the work in the expansion, not in the macro. | |
| 13.6.2 Evaluating Macro Arguments Repeatedly | The expansion should evaluate each macro arg once. | |
| 13.6.3 Local Variables in Macro Expansions | Local variable bindings in the expansion require special care. | |
| 13.6.4 Evaluating Macro Arguments in Expansion | Don't evaluate them; put them in the expansion. | |
| 13.6.5 How Many Times is the Macro Expanded? | Avoid depending on how many times expansion is done. |
