OOP was already implemented in Borland Pascal.

But what has all this to do with the concept of packages? The concepts 
used in TP where enough to allow arbitrary complex applications. And my 
main critic about all this is, that even when new concepts are 
introduced they should be rock solid. This looks more like a design study.

That's exactly what I did. I used Larazus to create a console 
application. I then added my general purpose unit to the uses clause. 
Then compile failed with an error message that had nothing to do with my 
program or unit.

Not true.

No. But you expect me to scan the brain of the programmers of the LCL to 
find out why I get this error message.

It seems they are not.

I did not.

I don't know. But still what I did was a standard thing:

*) Write a unit
*) Create a program (via Lararus) that uses the unit (which I use in 
nearly all programs)

What is wrong with this?


To sum it up:
If I use a unit GRIDS in a unit and a program uses this unit how should 
I know that this program has to use the unit INTERFACES? Why is this 
unit not required in my unit but in my program? That's completely 
rediculous. Why does the existing rock solid unit concept no longer 
work? It seems some other concept has broken it.
