-This is arguably the cleanest option for retrying but is blanketed with the negative stigma of using a ''goto''.+While this is arguably the cleanest option, it still requires the developer to define and manage a label which over several refactors might gradually move further away from the top of the ''try'' line. This implementation also makes it easy to accidentally execute any code after the label & before the ''try'' for each retry which is not entirely obvious at first glance.
