Unfortunately, the proxy does not carry any size information about its associated chare array.

To elaborate on this, from the system's perspective, the number of elements in a chare array is a distributed, dynamic property. Sequential code running on any one processor literally cannot provide a correct value.

For arrays that are static because the application knows so, the application can just as easily preserve and communicate that information by its own means.

Yep, the question arose when I needed to get that information inside library which receives only proxies of chare arrays (created in user code).
