It gives it a more structure that I think the “case” and “default” need and it would encourage indenting which I think helps a lot. But I think it might not be a bad thing to require the parenthesis. for the switch like flavor. I think parenthesis are better because it is an expression and it should feel more like a function, but that is open for debate. </div><div class=""><font color="#5856d6" face="Menlo" class=""><span style="font-size: 11px;" class=""><br class=""></span></font><span style="color: rgb(187, 44, 162);
