Then why people are defending separate spec files so hard?

Of course they're coupled, they're views of the same thing (just like 
private types and full types are views of the same thing).

I was referrring to coupling *between* units. The specification of a unit 
typically depends only on a small number of other units (sometimes even 
none), while the implementation typically depends on many more 
(language-defined packages, implementation helpers, etc.). That's the 
coupling I'm worrying about, as it matters in a number of ways.

Which would appear to be the same. :-) Since you belittle or ignore any 
serious argument, there's really no possibility of continuing. (It's OK to 
disagree, it's not OK to ignore all or [as in the case above], twist 
someone's discussion point into something unrecognizable.

The truth hurts. So far as I can tell, no other language has really tried to 
"get software engineering right". It's possible, of course, but everyone 
either is trying to graft engineering onto some preexisting base without it 
(C++, Java) or is building something that's more about fast construction 
than engineering (Python).

Good for them; they're not suitable for Ada if the truth bothers them that 
much.
