note chrestomanci <blockquote>But with strict that already doesn't compile. When you use strict, "once" usually becomes pretty irrelevant.</blockquote> <p>Mostly yes, but not if you refer to a fully qualified varable from another package. For example, when I am debugging my code, I often put <c>DB::single=1</c> at various places. Sometime I leave those line in production code inside assert like error checks, as a kind of assert that will only go off when debugging.</p> <p>I have found that those lines will trigger the "once" warning, which is irritating.</p> 1007936 1007940
