I think more escape hatches (@localnogc?) may help with the delegate situation you related.

```d
void registerCallbackSystem(void delegate() @system cb) @system;

...GC however.

But you can create a delegate yourself just fine.

In fact if you...

...delegate() @system cb) @system;
	void registerCallbackSafe(void delegate() @safe cb) @safe;
	void registerCallbackNoGc(void delegate...

...to keep the ``scope`` stuff on the delegate wrt. ``@safe`` as part of the weakening...
