Comment on Perspective: "Why C++ Is Not 'Back'" by gast128
I have a love-hate relationship with c++. I like the plain abstraction, its syntax and its value semantics. On the other hand I cannot appreciate the following things:
- compilation speed. In my work we have a 100 project solution, which takes 1 hour to build. We already use pch and all the compilation tricks. Other people here use c# and that compiles in minutes. Is it related to all the Boost template stuff, or is MS deliberately holding back c++ compilation?
- templates. They are very handy but there are many dark corners. When we upgraded to vstudio 2008 we encountered a problem which took us days. It turned out to be a non obvious issue which was correctly rejected.
- c++ tendency to allow redefinition of variables in various scopes. Also with overloads there are many pitfalls.
- universal references. I am not sure who voted the current syntax in. The rules of turning a rvalue into a lvalue are not obvious.
- backward compatibility is good for the short term (everything stays compilable) but blocks long term evolution. I wouldn’t mind if a proposal break old code if that would improve build speeds (e.g. in the template syntax). Ofc there is many c++ code written, but can’t this be solved by compiler flags? K&R C has also died.
