What's wrong with C++?
by Bartosz Milewski
Some time ago NWCPP (Northwest C++ Users Group in Seattle) organized a public panel on the future of C++, with Scott Meyers, Herb Sutter, and Andrei Alexandrescu. I started thinking about C++ and realized that I wasn't that sure any more if C++ was the answer to all my problems. I wanted to ask the panelists some tough questions. But I was there for a big surprise--before I had the opportunity to say anything, they started the criticism of C++ in the earnest--especially Scott.
One of the big issues was the extreme difficulty of parsing C++. Java and C#, both much younger languages, have a multitude of programming tools because it's so easy to parse them. C++ has virtually nothing! The best tool one can get is Microsoft Visual Studio, which is really pathetic in that department (I haven't tried Eclipse). Apparently, VS uses a different (incomplete) parser for its browser than it does for its compiler, and that's probably why it can't deal with namespaces or nested classes. When you search for a definition of a function, you get a long list of possible matches that don't take into account any of the qualifications of the original query. Finding all callers of a method is so unreliable that it's better not to use it. And these are the most basic requirements for an IDE. By the way, the Help engine seems to be using yet another parser.
I talked to John Lykos at one of the conferences, and he told me that he would pay big bucks for a tool that would be able to tell what header files must be included in a given file. That was many years ago and to my knowledge there still isn't such a tool. On the other hand, there are languages in which the programmer doesn't even have to specify include files, so clearly this is not an unsurmountable problem and it's only C++ that makes it virtually impossible.
Complex programming problems require complex languages. An expressive language helps you deal better with the complexity of a problem. I believe there is some proportionality between the complexity of the problem and the complexity of the language. But if a language is disproportionately complex, it starts adding complexity to the problem you're trying to solve instead of reducing it. There are endless examples of unnecessary complexity in C++.
Accidentally, the parsing difficulties of C++ might be the biggest roadblock in its evolution. In principle, changing the syntax of the language shouldn't be difficult, as long as you can provide good translation tools. You can look at syntax as a matter of display, rather than its inherent part. Just like you have pretty printers that format your code, you could have a pretty viewer that shows C++ declarations using Pascal-like syntax. You could then switch between programming using the rationalized syntax and the traditional syntax.
As long as C++ gurus live in the clouds of the Olympus, they won't see the need for this kind of evolution. That's why C++ becomes more and more elitist. In the future, people who do NYT crossword puzzles and the ones who program in C++ will be in the same category.
Very smart people keep writing books with titles that read like "Esoteric Nooks and Crannies of C++", or "More Bizarre Pitfalls of C++". Or puzzles that start with "What's wrong with this code fragment that to all normal people looks perfectly OK?". You don't see such publications in the Java or C# community. C++ is becoming a freak language that's parading its disfigurements in front of mildly disgusted but curiously fascinated audience.
"So you have to put a space between angle brackets? How bizarre!"
"Are you telling me that you can't pass an instance of a locally defined class to an STL algorithm? How curious!"
"Talk to me dirty! Tell me more about name resolution!"
"Pardon my French, Is this specialization or overloading?"
