// This file holds a list of reserved symbols for the Rhai language.
//
// The mapped attributes are:
// - is this a reserved symbol? (bool)
// - can this keyword be called normally as a function? (bool)
// - can this keyword be called in method-call style? (bool)
//
// Generate the output table via:
// ```bash
// gperf reserved.txt
// ```
//
// Since GNU gperf does not produce Rust output, the ANSI-C output must be hand-edited and
// manually spliced into `tokenizer.rs`.
//
// This includes:
// * Rewrite the C hashing program (especially since it uses a `switch` statement with fall-through)
//   into equivalent Rust as the function `is_reserved_keyword_or_symbol`.
// * Update the values for the `???_RESERVED_???` constants.
// * Copy the `asso_values` array into `RESERVED_ASSOC_VALUES`.
// * Copy the `wordlist` array into `RESERVED_LIST` with the following modifications:
//   - Remove the `#line` comments
//   - Change the entry wrapping `{ .. }` into tuples `( .. )`
//   - Feature flags can be incorporated directly into the output via the `cfg!` macro
