The Ada way is ok for simple I/O.

What about when you want to produce a formatted report ?

Regardless of whether you keep the current I/O method only or add
something printf style, it's far more logical and cleaner for the
actual internal to external conversion to be conceptually a part
of the data type rather than yet _another_ package within Text_IO.

(Basically, you need a seriously enhanced version of 'Image with Text_IO
providing the basic non datatype specific I/O framework and the data type
itself doing the formatting/conversion to the requested output length,
editing and precision when applicable.)

This stuff belongs with the data type, not with some Text_IO package.

The same types of comments apply to input as well.

Simon.
