My gosh, you *almost always* put the spec and body in the
same file??? that undermines one of the most important links
between file structure and modular structure of your program.
AQ&S specifically recommends putting one unit per file, and
nearly all coding standards I am familiar with in Ada require
this arrangement.

which is why we have not bothered to implement multiple units
per file. First, it is quite tricky, because of the problem of
instantiating from another unit in the current source file, but
mostly it would not be used very much, because most Ada users
prefer one unit per file anyway. We consider gnatchop a good
enough solution for the small number of exceptions to this rule,
so multiple units per file is low down on our enhancement list.

By the way: in GNAT a compilation environment can contain a
subunit and body with the same unit name (this is a new feature
in GNAT 3.12), and that's QUITE a strange situation, where
default file naming sure does not work!
