For me the problem in code formatter with comments is what to do with
them? They can occur at any whitespace, and in many cases I see no way
to represent them in formatted code nicely. (There are some personally
disguising formatting styles in a wild which do not conform with style
reformatter wish.)

For example:

  local function
  -- bla-blah
  foo(  a -- parameter "a"
      , b -- parameter "b"
     )
    return   -- "return" returns values
           a -- ref to "a"
           + -- plus means sum
           b -- b!
  end

More mad cases may be constructed:

  local t = { [ --[[ hey, why not place comment here? ]] 1] = 1}

Simplest option is to drop comments at all. Other way is to group them
before parent statement. (I'm going to try latter in my code formatter
"lcf" someday.)
