These codes are syntax valid in parse.y ```ruby p{|a: b|} ->(a: b){} ->a: b{} ->a: {} ```

```ruby [a:1,,] [**a,,] ```

Assigning command call is allowed where rejected in parse.y

These command calls are rejected in parse.y but accepted in prism ```ruby 1 if a = b c 1 and a = b c a = b c and 1...

Feature request for an API to check if a syntax invalid code can be syntax valid by appending continuation tokens

It would be helpful if Prism have an API that works like this. ~~~ruby Prism.parse('1 + [').input_continuable? #=> true Prism.parse('1 + ]').input_continuable? #=> false Prism.parse('tap do').input_continuable? #=> true Prism.parse('end.tap do').input_continuable?...
