# typed: true

class A
  class << self
end

Observed output

s(:begin)
editor.rb:5: unexpected token "end of file" https://srb.help/2001
     5 |end
     6 |
Errors: 1

Expected behavior

Sorbet should produce a parse result, instead of an empty parse result.

---

This doesn't matter quite as much as other parse results, because adding this line will force us to take the slow path still, but at least error messages will get better (and if you didn't fix the syntax error fast enough, we might be able to start showing completion requests in the class body eventually).

Note that we already recover for most other forms of mismatched end. See the changes in #5383 for inspiration on how to fix this.
