| // |
| // Optionally, the user may also define: |
| // |
| // BENIGN_LANGOPT: for options that don't affect the construction of the AST in |
| // any way (that is, the value can be different between an implicit module |
| // and the user of that module). |
| // |
| // COMPATIBLE_LANGOPT: for options that affect the construction of the AST in |
| // a way that doesn't prevent interoperability (that is, the value can be |
| // different between an explicit module and the user of that module). |
| // |
| // ENUM_LANGOPT: for options that have enumeration, rather than unsigned, type. |
| // |
| // VALUE_LANGOPT: for options that describe a value rather than a flag. |
| // |
| // BENIGN_ENUM_LANGOPT, COMPATIBLE_ENUM_LANGOPT, |
| // BENIGN_VALUE_LANGOPT, COMPATIBLE_VALUE_LANGOPT: combinations of the above. |
| // |
| // FIXME: Clients should be able to more easily select whether they want |
| // different levels of compatibility versus how to handle different kinds |
| // of option. |
| // |
| // The Description field should be a noun phrase, for instance "frobbing all |
| // widgets" or "C's implicit blintz feature". |
