Implementation? What's this again? It's no longer enough to use a unit?
Sorry, but it seems that there is a very steep learning curve even for 
former (Turbo..) Pascal programmers.
I have to learn a lot just to be able to program with Lazarus. It seems 
to be for long term nerds only.
It has become nearly as complicated as C and relatives.

Everything. If it leads to such results this concept seems to be not 
very good.

Shouldn't these dependencies somehow be handled by the compiler/linker? 
Why is the programmer bothered with it? There could be a default 
"implementation" that would be used in these cases. Now the programmer 
has to investigate in the concept *and* how Lazarus/FPC handles it. Not 
very convenient.
