Are they going to register the range with the GC for scanning?
If so then fine. I do stuff where I've got deterministically allocated 
structs which can wind up having the only live references to other GC 
objects.

Though perhaps we could have 2 different functions, one that registers 
the object with the GC & one without. Being able to easily mix & match 
memory strategies is a great feature so it would be nice to still be 
able to easily do it, even if you make it all library functions with 
great big 'Danger Will Robinson!' stickers all over it.
