### `Binding`: separate local variables from implicit parameters[](#binding-separate-local-variables-from-implicit-parameters)

`Binding#local_variables` method now exclude numbered (implicit) parameters, and methods like `#local_varaible_get` raise an error for those names. Instead, new method group `#implicit_parameters`/`#implicit_parameter_get`/`#implicit_parameter_defined?` was introduced to refer to both kinds of implicit parameters (numbered and `it`).

* **Reason:** It was decided, that exposing numbered parameters as "local variables" is confusing and misleading (say, you couldn't call `_1 = value`, but accidentally `binding.local_variable_set(:_1, value)` worked). So the concepts were separated.

#### Methods for waiting for a ractor[](#methods-for-waiting-for-a-ractor)

Instead of `#take`, there are now `#join` (wait till ractor ends its execution) and `#value` (`#join` + provide the return value), and also lower-level methdods `#monitor` and `#unmonitor` that provide `Port`-based abstractions to implement `#join` and alike methods.
