It takes discipline to mix. Libraries would need to:
1. Be written for RC, transition to GC becomes free.
2. Written for finalizers, getting basic cleanup
3. Test for various mixes of RC/GC... How?
But you also need a fully precise GC to get proper finalzation...

Probably not worth it, easier to have GC only libs...

I am arguing in favour of task bound GC, which can b extended to 
task-group GC. The latter should roughly cover existing code 
bases that dont do anything fancy...

The key point however is that DMD ought to use the recommened 
sytem programming MM idiom (whatever it ends up being), then it 
is possible to argue pro et contra with some level of objectivity.

With no common ground, nothing will move...
