note LanX Do you have a clear definition for "construct"? from [doc://perlglossary] <c> construct As a noun, a piece of syntax made up of smaller pieces. </c> I think in this context it's supposed to mean "block of a loop". IMHO this discussion helps: [id://833015] From what I remember labels are only visible from the actual "frame" and parent frames. Frames are constructs which need an initialization like <c>sub</c>s or <c>for-each</c>-loops (remember the aliased loop-var!). That means you can't jump into these constructs and bypass initialization. But if you call another sub from within such a frame, that means after run-time initialization, you can <C>goto</C> back. So lables are a run-time thing. They belong to the dynamic scope like localized vars. EDIT: I think the deprecation is supposed to disallow jumps into other kinds of loops like <c>while</c>¹ or c-style <c>for</c>s , which have a "logical" but no "physical" initialization like frames. HTH!  <div class="pmsig"><div class="pmsig-708738"> Cheers Rolf </div></div> ¹) remember that naked blocks are internally just while-loops 1013574 1013574
