construction of the AST in 20// a way that doesn't prevent interoperability (that is, the value can be 21// different between an explicit module and the user of that module). 22// 23// ENUM_LANGOPT: for options that have enumeration, rather than unsigned, type. 24// 25// VALUE_LANGOPT: for options that describe a value rather than a flag. 26// 27// BENIGN_ENUM_LANGOPT, COMPATIBLE_ENUM_LANGOPT, 28// BENIGN_VALUE_LANGOPT, COMPATIBLE_VALUE_LANGOPT: combinations of the above. 29// 30// FIXME: Clients should be able to more easily select whether they want 31// different levels of compatibility
