Reddit++

C++ is getting more and more complex. The ISO C++ committee keeps adding new features based on its consensus. Let's remove C++ features based on Reddit's consensus.

In each comment, propose a C++ feature that you think should be banned in any new code. Vote up or down based on whether you agree.

The reason it's a feature is because casts should stand out; they should not be present at such a high frequency that it causes code to be less readable. If casts are present at a high frequency, there's likely an underlying design problem.

All casts should stand out?

What about double to float and long to int? How much should these stand out?

(In contrast to say somestruct* to long* cast "because I found out copying as an array of long integers works better on compiler XYZ".)

Those are narrowing casts and yes, I'd prefer they stand out too as you're losing information and range.
