How do I use arrays in C++?

What's the correct way to sort Python `import x` and `from x import y` statements?

Imports are generally sorted alphabetically and described in various places beside PEP 8.
Alphabetically sorted modules are quicker to read and searchable. After all python is all about readability.

Is std::unique_ptr required to know the full definition of T?
...s. However shared_ptr and unique_ptr are partial exceptions. Some, but not all of their members can be instantiated with incomplete types. The motivation for this is to support idioms such as pimpl using smart pointers, and without risking undefined behavior.
Undefined behavior can occur when you h...
