<p style="margin:0px 0px 1.2em!important">This now reads as: <em>This is a guard: x must be greater than zero, otherwise return</em>. The only issue is it has the same syntax as a break-label so becomes potentially ambiguous/confusing. Is there another way that could be achieved?</p></div></div>
</blockquote>The ambiguity could be resolved by disallowing keywords as labels. I don't use them much, though, so I'm not sure how much that would affect readability.</div><div><br></div><div>- Dave Sweeris</div><div><br></div></body></html>
