except where trait objects are involved. Part of issue #15349, though I'm leaving it open for trait objects. Cross borrowing for trait objects remains because it is needed until we have DST. This will break code like: fn foo(x: &int) { ... } let a = box 3i; foo(a); Change this code to: fn foo(x: &int) { ... } let a = box 3i; foo(&*a); [breaking-change]
