This allows to decou= ple logical and physical aspects of namespace designs. I agree that this is convenient. Is convenience in 'architectural elaborati= on' a good thing? I don't think so. The body of works exist to testify of t= he utter mess it can produce over the years. =20 But 'extension' through child package, present in the filename, is 'self do= cumenting' in Ada. C++ namespace can be anywhere regardless of file naming.= .. often very confusing about what is tied to what. At directory level you = cannot figure out the design layout. In Ada you can get pretty much the who= le picture just from that inspection. This is huge for reasoning. Maybe enforcing the explicit merging of designs in Ada is a very good thing= in the long run. It forces the team members to take decisions early and de= dicate to a real solution, one that they will live with. I know this could = be very heavy at time and I can easily figure why some probably ditched Ada= just because of such lack of convenience --> They just want to code. =20
