Well, this is at the wrong level for a compiler optimization. How
could it do better than that? It would have to do exactly the same
things behind the curtains. It's not the compiler's business to
handle stuff you can do at the user level with similar efficiency.

[And I'm pretty sure it doesn't pay off either way. Rethink the
whole thing and find easier ways to do what you're really trying
to achieve. This sounds a lot like architecture astronautics.]
