* Anonymous functions (in Rust closure syntax). Simplifies creation of single-use ad-hoc functions.
* Currying of function pointers.
* Auto-currying of anonymous functions.
* Closures - auto-currying of anonymous functions to capture shared variables from the external scope.
* Capturing call scope via `func!(...)` syntax.
New features
@@ -21,7 +21,7 @@ New features
* Anonymous functions are supported in the syntax of a Rust closure, e.g. `|x, y, z| x + y - z`.
* Custom syntax now works even without the `internals` feature.
* Currying of function pointers is supported via the new `curry` keyword.
* Automatic currying of anonymous functions to capture environment variables.
* Automatic currying of anonymous functions to capture shared variables from the external scope.
* Capturing of the calling scope for function call via the `func!(...)` syntax.
* `Module::set_indexer_get_set_fn` is added as a shorthand of both `Module::set_indexer_get_fn` and `Module::set_indexer_set_fn`.
* New `unicode-xid-ident` feature to allow [Unicode Standard Annex #31](http://www.unicode.org/reports/tr31/) for identifiers.
