Rightward assignment inside "case ... when" produces invalid syntax

[hpello]

Hey there!

I noticed the following behaviour, when using rightward assignment => inside a case ... when:

puts SyntaxTree.format <<~RUBY
  case [0]
  when 0
    { a: 0 } => { a: }
    puts a
  end
RUBY

produces:

[0] =>
  when 0
    case { a: 0 }
    a:
    end
    puts a

It seems like the rightward assignment is moved to the top... producing an invalid ruby syntax.
Do you know where this may come from?

Ahh this is a problem with the parser. Just found the fix, thanks!
