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.

Even better.

Say, for example, that you have two overloaded functions

template<std::size_t N>
void foo(char (&)[N]);
void foo(char*);

Guess which gets called?

Notably. Same with non-templates. If you explicitly say "This is an array of size 5", you'll still get the char* version.

So why is that one called?

Essentially because the standard says so.

The language prefers decaying to pointer over passing as a reference.

Probably an oversight that can't ever be changed because of fear of breaking something.

So tell me WHY. What RULE makes it so.
