is it possible to have defn compile to zig?

gut feeling says yes. Even if we can't have a jitting zig compiler until https://github.com/ityonemo/zigler/issues/245, I think fusing operations should be reasonable to do, and at least it will cut out the (potentially expensive) process of marshalling and unmarshalling your tensors from erlang resources.

Start by reviewing the defn compilation path and the linked Zigler issue #245, then determine how tensor operations and Erlang resources are currently handled. The issue does not name files or tests, so completion would first require an agreed scope for Zig compilation or operation fusion and a concrete validation plan.
