This is not a special case any more than disallowing access of shared 
data from a pure function is a special case.

In fact, you could allow inout variables as static or globals, but just 
couldn't copy them to local inout variables (except full value types).

The point is that between 2 different calls to inout, the wrapper means 
something different. A global/static persists between calls.
