Chapter 4

1. Static types allow the compiler to generate type-specific optimization, making the compiled code more efficient.
2. A memory view belongs to Cython's interface, which helps it work with different data types such as byte, bytearray, or array.array easier. Specifically, it offers a universal interface that simplifies the process of accessing the values that are stored in these different data types.
3. To profile Cython, we can use the annotated view to identify hard-to-find interpreter-related calls, as well as the familiar cProfile tool.
