The following code used to compile with -dip1000 but no longer does since

 nogc void g(T)(scope T args) {}

 nogc void foo(T)(scope T args) {
    scope dg = () { g(args); };

void main() {

dmd -dip1000 onlineapp.d:
onlineapp.d(3): Error: function `onlineapp.foo!string.foo` is ` nogc` yet
allocates closures with the GC
