Error in setting default value for option types to `none` in nested struct

[impopular-guy]

Describe the bug

• Setting default value of option type to none causes error. Anything else runs successfully.
• Also it prints incorrectly

  d := Data{} // see reproduction steps for definition
  println(d)
  println(d.a)
  

  gives the output

  Data{
      a: 0
      b: 1
      c: 0
  }
  Option(error: none)
  

  I think it should be

  Data{
      a: none
      b: 1
      c: none
  }
  Option(none)
  

Expected Behavior

Should run successfully with a warning.
