paren:balanced?

• (paren:balanced? text start end parens quotes comments) -> boolean
      text : (instance text%)
      start : exact-integer
      end : exact-integer
      parens : (listof (cons string string))
      quotes : (listof (cons string string))
      comments : (listof string)

  Returns #t if the text in text between positions start and end is balanced. The text is balanced if there are no unclosed parenthses or quotes, there are no closing parentheses that do not match an open parenthesis, and there are no mis-matched parentheses.

  This uses paren:forward-match.
