C++ is adding lots of new features. But the trouble is, the old features remain, 
and people will still use them, and suffer.

Examples:

1. The preprocessor remains. There has never been a concerted effort to find 
replacements for it, then deprecate it. It's like allowing horse-drawn carts on 
the road.

2. Strings are still 0-terminated. This is a performance problem, memory 
consumption problem, and is fundamentally memory unsafe.

3. Arrays still decay to pointers, losing all bounds information.

4. `char` is still optionally signed. What a lurking disaster that is.

5. What size is an `int`?
