| |
| <p>Operators may be binary, unary, functions, special syntactic constructs |

| constructs like implicit type conversions. The syntax of the operator is |
| really irrelevant, because row-expressions (unlike |

| <p>It's not often necessary to sub-class this class. The smarts should be in |
| the operator, rather than the call. Any extra information about the call can |
| often be encoded as extra arguments. (These don't need to be hidden, because |
