[Oberon] Oberon for a C++ user.

[Skulski, Wojciech]

Richard:

  with all due respect, I kindly disagree. First, I am not sure if there are many end users at this point. Second, the problem is common to all implementations, including BlackBox if I understand correctly. It would be good to pinpoint the origin of the problem and to find an elegant solution, if at all possible. It would benefit the broader community. Third, the Oberon and BlackBox claim to fame is rapid and safe development without the dreaded "segmentation violation" which is plaguing the C family. But here we have exactly that.

I do not know if you are a teacher, but if I was one then I could not teach good and safe programming techniques with Oberon only to say to students "you know what, it is crashing like everyone else". It is either one way or another. 

Of course we can live with the crashing implementation, but then we can as well live with C like everyone is doing. At the end, there is a "reset" button to the rescue. Let's just use it and forget the elegant design.

Just my opinion.

I think, it would not make sense to invest a lot of effort just to
eliminate the unsafety of explicit module unloading.

After all, an end user of the Oberon System will just use applications
with automatic on-demand module loading and never have to unload older
versions of these modules.

Only programmers have to do that during the development of a module. And
they can already use unsafe features of the programming language simply
by importing the System module, provoking similar effects e.g. via
unsafe type conversions.

Thus, eliminating the module unloading unsafety would not significantly
improve the stability of the system.
