I copied that message verbatim from ksh93.  Can still change it, but
does it really matter?

See previous message.

The point at which it's necessary to catch that error would have to

to determine the thing being subscripted.  That seems like an
unnecessary amount of work.

How about
  can't change type via subscript reference
