I've been following this discussion, but now I'm a bit confused.

If program A contains ar << T and program B contains ar << Tptr, can 
program C read from files produced by both programs A and B? (C would 
thus require ar >> T in the code that reads files produced by A and ar 
 >> Tptr when reading files produced by B.)

I certainly think it "ought to", but as I understand it from the 
discussion, only the files produced by program B would be readable by 
program C.
