Consider we add a library slice type called RCSlice!T. It would have

underlying the slice is freed. The underlying allocator will be the GC
allocator.
Now, what if someone doesn't care about the whole RC thing and aims at
convenience? There would be a method .toGC that just detaches the
slice and disables the reference counter (e.g. by setting it to
uint.max/2 or whatever).
Then people who want reference counting say
auto x = fun();
and those who don't care say:
auto x = fun().toGC();
Destroy.

RC need GC to collect loops. So you want to have the GC at the lowest
level.
Correctamundo.
That being understood, I'd rather connect things the other way around.
auto x = foo();
auto x = foo().toRC();
I don't know how to implement that.
