Middleware for handling `multipart/form-data`.

// never matches and silently disables the limit. Reject such values up front.

    var value = limits[key]

    if (value == null) return
    if ((Number.isInteger(value) && value >= 0) || value === Infinity) return

    throw new TypeError('Expected limits.' + key + ' to be a non-negative integer or Infinity')
  })
