    yes you can wrap stuff in arrays, but that is making the callsite look ugly for a function definition problem. The solution "return ,$array" is just weird

  # .SYNOPSIS
  # Why do I need to type .SYNOPSIS above here, and yes that extra line is too many
  function foo(
      # but here its just obviously a comment for a parameter
      [string] $param=""
  ) {
      $param
  }
