And what about Erlang ??

Once again, I've been puzzled by Sebesta's "Concepts of Programming languages" book. I've just read the chapter on language-level support for concurrent programming and there's not even a single line on Erlang. I can't figure out how that's possible.

Now waiting to see if Erlang is going to appear in the chapter on functional languages, but for some reason, I have a bad feeling about this...

Concepts of Programming Languages

These days, I'm reading "Concepts of Programming languages", 8th edition, by Robert W. Sebesta (Addison Wesley). In the category of programming languages comparison books, this is all in all a fair one, especially after having read the crappy "Comparative Programming Languages", 3rd edition, by Clark (Addison Wesley).

As in all those similar books, the room for Lisp is obviously miserable, but that is not very surprising. At least Sebesta seems to know something about it... but wait ! That was until yesterday.

Yesterday, I read chapter 12 (Support for Object Oriented Programming), and this reading pretty much ruined my fun, my evening, and the little consideration I had for the author. On page 508 you can find this:

CLOS, an object-oriented version of Lisp, also supports functional programming.

And there's even a reference to the CLOS specification reference document.

Since the book is suddenly turning the Big Circus way, let's not stop just here. A couple of pages later, there's an interview of Bjarne Stroustrup, for whom having invented C++ is obviously not enough, and so claims that

Currently, C++ is the best language for multi-paradigm programming.

That's it boys. These guys have no clue whatsoever.
