CL (where all lower bounds are 0) doesn't round-trip empty arrays
either.  Arrays with dimensions (0 0) and (0 2) both print as #2A(),
which is read back with dimensions (0 0).  However, an array with
dimensions (2 0) prints as #2A(() ())

The element type is also discarded on output: if you read them in, you
always get an array with the generic storage class. SBCL has an
extension for this.
