I'm experimenting with making a private type limited. Unfortunately
doing this toasts the default definitions for the stream attributes for
that type. But I *liked* the default definitions for the stream
attributes. In fact, I need 'Input, 'Output, 'Class'Input, and
'Class'Output.

So just write my own clones of those attributes, then do a "for
typename'{Attribute} use", right? Well, the problem is I can't figure
out is how to (re)make 'Class'Input myself. Its definition from the LRM
is:

First reads the external tag from Stream and determines the
corresponding internal tag (by calling
Tags.Internal_Tag(String'Input(Stream)) -- see 3.9) and then dispatches
to the subprogram denoted by the Input attribute of the specific type
identified by the internal tag; returns that result.

So how do I write Ada code to do this? I hope I'm missing something
simple.
