I would prefer instead the developers either manually reorder the values, and perhaps that an operator be added to explicitly perform automatic reordering. Perhaps a tilde? Like so:<div class=""><br class=""></div><div class=""><font face="Monaco" class=""><span class="Apple-tab-span" style="white-space:pre"> </span>let a = (x: 1, y: 2)</font></div><div class=""><font face="Monaco" class=""><span class="Apple-tab-span" style="white-space:pre"> </span>var b: (y:Int, x:Int)</font></div><div class=""><font face="Monaco" class=""><br class=""></font></div><div class=""><font face="Monaco" class=""><span class="Apple-tab-span" style="white-space:pre"> </span>b = a // warning</font></div><div class=""><font face="Monaco" class=""><span class="Apple-tab-span" style="white-space:pre"> </span>b = (x: a.x, y: a.y) // explicit, manual reordering</font></div><div class=""><font face="Monaco" class=""><span class="Apple-tab-span" style="white-space:pre"> </span>b = ~a // implicit, automatic reordering by label matching (still warns/errors on type mismatch)</font></div><div class=""><br class=""></div><div class="">As for any other changes however, I think these should be addressed in their own proposals as I think discussion is getting too broad and confusing IMO.</div></body></html>
