...then it's a sign that you're not teaching an obscure enough programming language. Using C++ is like asking the students to cheat. You want to require all answers in Unicon, or Lambda Prolog, or (worst of all) POPLOG-11.

Not really. You end up with a lot less effort
than using Prolog, because you get all of Prolog's
functionality, plus direct access to a more general
underlying framework. See, for example, Schelog
or Poplog.

Hey, why reinvent the wheel? A dog might not be
able to walk past a tree without pissing on it, but
I would hope that a software developer could do
better than that.... Call me a cock-eyed optimist.

Used mostly for teaching AI, it has a lot of weird features. It also let programmers to manipulate the stack. The VM, called "poplog", supports multilanguage (.net invented 20 years ago) with ML + Prolog + Pop-11 + Lisp implementations off the box, and allows incremental compilation (very similar to CMUCL).

Here you will find an online primer. Another good site.

My history of languages learnt are (roughly):

1. Spectrum BASIC
2. Z80 Assembler
3. 68000 Assembler (on my Sinclair QL)
4. POP-11
5. Prolog
6. Standard ML
7. Modula-2
8. C
9. C++

Not including shell scripting languages etc.

I'm now a Senior Software Engineer working almost exclusively in C++ and I feel my varied history of languages learnt has greatly contributed to making me the seasoned professional I now am.

The finer point I'm trying to make is that I've engineered C/C++ on boxes ranging in size from clusters of 4GB RAM, 8 x 1GHz POWER4 CPU RS6000 AIX machines all the way down to mobile phones and I feel learning a couple of assembly languages was an appropriate and valuable part of my personal development as a Software Engineer.

Smalltalk: You send the message shoot to gun, with selectors bullet and foot. A window pops up saying Gunpowder doesNotUnderstand: spark. After several hours fruitlessly spent browsing the methods in Trigger, FiringPin and IdealGas, you create ShotFoot, a subclass of Foot with a new instance variable bullet hole.
