Oh, just ran into this gem. I've always found Bjarne Stroustrup certainly brillant, but a bit nuts. Just a personal opinion of course. But after reading this, which admittedly is now a bit old, you'll have a hard time convincing me he isn't - I mean, nuts.

Note the date of the referenced "AT&T Labs Technical Report no. 42, April 1,1998".
This being said, I'm still not convinced if this is April fools or not, because the content is not
that different from what C++ actually became. The problem with Bjarne Stroustrup is, you
can't know. It's entirely possible the whole C++ is just a piece of modern art, a psychological experiment, or pure trolling. Nobody knows if Bjarne Stroustrup ever was serious, or if he is laughing in his beard, watching the world go really serious with C++.
Yet it is entirely possible to successfully use C++ to write large and even somewhat maintainable programs. But the human is amazing. Given enough time and motivation, one could make the man go to the Moon using the Brainfuck language entirely.
