You can get the same information by using a temporary variable, and
then the who{,s} functions don't have to include the extra complexity
of looking at argument names and calling eval on them.  For example

  tmp = A.a; whos tmp

Also, what information from something like "whos x.a{4}" is not
available in some other way?  For example

  size (x.a{4})    (same as Size in whos output)
  sizeof (x.a{4})  (same as Bytes in whos output)
  class (x.a{4})   (same as Class in whos output)
