But that's the problem, if e is a dynamic array, then it can potentially
be modified through the original reference after being assigned.

Ideally, I'd need e to be a reference to an immutable type. But that
requires a way of converting an arbitrary type to its immutable form,
which I don't know how to do in a generic way.
