I think that a large part of that C syntactic elegance is an illusion.
From my experience, I want my code to look very simple to read and
clean every time this is possible. I want it to be easy to port to
other languages, because I have do it often enough. C code that uses
lot of pointers is often bug-prone, messy and hard to safely translate
to other languages.
There are situation where pointers are necessary or are better than
the alternatives, or they give the needed flexibility, so I prefer a
language with pointers, but in a well designed language those
situations are not common, and I think raw pointers should be avoided
when they are not needed. I have debugged enough C code to be rather
sure of this. Good luck with your pointers.
I rarely use pointers in D, its arrays are a better concept. I just
remarked that C code using pointers is sometimes more elegant than
equivalent D code using arrays or ranges, and that it is a little bit
unfortunate that we have all that while(*p && *p++ == --*q++){} stuff in
the D grammar without the possibility to use it.
Well you can do that in D. The thing is to not do it implicitely because
it is a dangerous behaviour and you should go into this only if you know
what you are doing and not by mistake.
