Harro, why not use simple procedures (not methods) instead of initialization methods which you'd like to invoke as supercalls?
The only objection I see is a somewhat more verbose code (module names have to be called) -- but then there can be no confusion in regard of which procedure is being called.
An Init for a LIMITED type ought to be hidden anyway within a factory procedure/method (belonging to another type).
Also, LIMITED types are introduced to ensure that the creator can guarantee their invariants, the client is not supposed to have access to that.
Conceptually, EXTENSIBLE methods go hand in hand with EXTENSIBLE records.
The same for ABSTRACT.
To me, the EXTENSIBLE methods and types look like an unnecessary complication, opening gates for confusing code.
Chris, could you expand a little on why you must use EXTENSIBLE's within .NET?
Thanks,
Cheers
Fyodor
