Hmm.  My code has cases of:
      for X'Address use at mod 4;

I've also broken abstractions by using 'Address to obtain access to the details
of an otherwise private type--those are old, and can be updated to use child packages.

I also seem to recall that a lot of the NUMWG work uses address clauses when pulling floating point numbers apart--and putting them back together.

and I also have some mixed Fortran and Ada that uses at Foo'Address + 24 or the like to deal with Fortran common blocks that are really overlays. (For example, one declaration has the common block as an array, another converts it to a vector.)

Are all of these deprecated now?
