 Bug fixes
 ---------
 
 * Unary prefix operators `-`, `+` and `!` now bind correctly when applied to an expression. Previously, `-x.len` is parsed as `(-x).len` which is obviously counter-intuitive.
 * Indexing of namespace-qualified variables now work properly, such as `path::to::var[x]`.
 * Constants are no longer propagated by the optimizer if shadowed by a non-constant variable.
-* Constants passed as the `this` parameter to Rhai functions now throws an error if assigned to.
+* A constant passed as the `this` parameter to Rhai functions now throws an error if assigned to.
 * Generic type parameter of `Engine::register_iterator` is `IntoIterator` instead of `Iterator`.
 * Fixes parsing of block comments ending with `**/` or inner blocks starting with `//*`.

 * `AST::iter_functions` now returns `ScriptFnMetadata` which includes, among others, _doc-comments_ for functions prefixed by `///` or `/**`.
 * _Doc-comments_ can be enabled/disabled with the new `Engine::set_doc_comments` method.
-* A new feature `metadata` is added that pulls in `serde_json` and enables `Engine::gen_fn_metadata_to_json` and ``Engine::gen_fn_metadata_with_ast_to_json` which exports the full list of functions metadata (including those inside an `AST`) in JSON format.

 * A functions lookup cache is added to make function call resolution faster.
 * Capturing a constant variable in a closure is now supported, with no cloning.

 * A _look-ahead_ symbol is provided to custom syntax parsers, which can be used to parse variable-length symbol streams.
