But the example with multiple selectors and & at the start is unclear due to the precedence of the @nest operator over the comma: /* @nest always */ @nest & + .baz, &.qux { color: red; } It's clearer perhaps with different nesting, but that's fragile and a pain: /* @nest always */ @nest & + .baz, &.qux { color: red; } At least with option 1 you only end up with this issue in the uncommon case of multiple selectors and a non-leading &. /* @nest */ & + .baz, &.qux { color: red; }
