Why did we need the databases in the first place?

There are some (rare) occasions, when private members drag new dependencies that you don't want the user of your class to know about. You can also do "pImpl", which is similar, if not worse, in terms of boilerplate, but doesn

Having 100% code coverage is like having 0 warnings (although it certainly is a lot harder). In this situation, your tools are not telling you "all's good", but rather "I can't detect anything suspect here".

See the paper "On the Danger of Coverage Directed Test Case Generation". http://link.springer.com/chapter/10.1007%2F978-3-642-28872-2... The idea is that a test suite can have 100% coverage and still be a ver

Embedded C programmer here. What you say is technically true, however, wiring interfaces and vtables manually in C is a real PITA, to the point that you think twice before introducing a new interface between two components. OO languages mak

Just because a language feature is hard to implement doesn't mean we should abandon it. I'm not going back to explicit error handling.

Please note that, GC or not GC, you still can have deterministic destruction (e.g RAII).

They work fine. Everything is captured by reference, and is ultimately garbage collected. Unlike C++, you're not required to use a special "local function" syntax.

I don't get it. AFAIK the goal of optimizers is to generate faster code while preserving the initial visible behaviour. If the initial behaviour is undefined, what can an optimizer try to preserve? Could someone give an example on how

The run-time cost of C++ abstractions is also NOT what I was talking about. I was talking about how C++ requires more communication with your team, because some "abstraction" features you might not want (RAII, RTTI, polymorphic di

Like C, C++ doesn't force you in any way to have extra useless abstractions over the hardware. The rest of your team do (and C make this way harder).
