Yes, but not for the reasons you think. A programming language stinks if: 1) You can't readily hire a replacement programmer 2) It doesn't have a quality debugger As for the rest, I pretty much disagree with most of your points, but won't bother arguing here except to say that anyone who says "forget structs" and "avoid using pointers" has no credibility whatsoever in my book.

There aren't "bad" languages so much as "toy" languages. As I see it, there are three types of languages... 1) Languages that can be used to write real software. 2) Languages that can kind of write software, if you don't have the time/knowledge/infrastructure to go with #1. Just don't try to do anything complicated, or you'll be ripping your hair out in record time. 3) Languages that should stay in academia and never, ever emerge. Useful to learn principles, perhaps, but just don't belong in the real world.

It is inherently poor practice. As someone "wiseman" has said, do not program in the language, program into the language. You clearly demonstrate that. Now 5 points for those who can name who is the "wiseman", I am quoting.

Why would you forgo pointers? They are very powerful and if you think references are safe, you are delusional (a poster here hates references so much, he advocates never using them!) Moreover, they are there and pretending they're not is pure foolishness. They key isn't to avoid using pointers, but to understand them (point being that it is my experience that most programmers who rant against pointers don't understand them.)

Not unlike goto, pointers are powerful and very useful, but almost just as dangerous. References are not 100% safe, granted. But in my experience, the pointer / reference cockup ratio has been somewhere around 1000 / 1. It takes a lot more effort to defeat reference consistency than to come up with pointer errors - that is, provided you take the time to rethink you programming paradigms (e.g. forget return values, think output arguments).

I never advocated doing away with pointers entirely, but merely not using them where they're not needed – which in C++ is an awful lot of places.

Wow, be a little more clueless and condescending. C++ isn't one of those languages, so why pretend it should be. If you want automatic memory management and all that goes with it, use a language that gives that to you. Don't try to force C++ to be something it isn't. You way overestimate the safety of references and apparently ignore their many other downsides. The resistance to pointers creates seriously awful code. If you want the features of C#, use C#. However, needless bloating up code because you might shoot yourself in the foot in C++ is absurd and ignores the fact that C++ is relentless in not only handing you the gun, but loading and cocking it as well. :)

Never meant to. My point is that, in principle, abstracting away pointers is not bad. C++ has numerous facilities for doing it, from references to
autopointers to the STL collections; so it's hardly about "forcing" anything, more like putting to use support that's already there. Actually the point I've been trying to make all along is "don't program C++ as if it was C". C++ has several features that simplify memory management, and they're much easier to leverage when you restrict pointer usage. -

A language that's bad for me to use is one that gets in my way or frequently annoys me even when I make repeated efforts to adopt its "style". Good code can be written even in "bad" languages (with a few exceptions), given enough careful attention, but for some languages, it's typically just not worth the effort. (Granted, different people have different opinions on which languages those are.) That being said, I've been known to willingly write code even in the languages I dislike, because there was money to be had from it.

Exactly! Much like a butter knife, references are cheap, straightforward and perfectly suited for the task they were crafted for. Of course, when employed outside their original scope they may not feature so stellarly, but generally they won't blow your face off (though you can hurt yourself with one, if you try hard enough). Likewise, pointers are just like handguns...
