Hello,
I see the opposite comments in curly braced languages about circular
dependencies and (lack) of reuse all the time. It's a question of <lack>
of design which paints them into corners regularly.
The fact that the compiler enforces the acyclic properties of the
dependency graph is, in fact, a huge advantage for the pascal programmer.
Two design techniques not mentioned in the thread, and very useful for
thinking large scale programming are:
- the inversion of dependencies, (which leads to creating interfaces and
abstract classes),
- the use of (self-designed) events.
Best regards,
Thierry

Hi
Circular references are a real problem in real (non-trivial) Object Pascal
programs. You could look at this thread:

The solution is to copy everything into one big unit. That's what everybody
finally does after fighting with interfaces, abstract base classes and type
casting.
