How to use bit_cast to type pun a unsigned char array

In C++20 we will hopefully get bit_cast see the proposal and reference implementation. This utility should give us a simple and safe way to type pun.

The one issue I ran into with this utility is that is requires the size of the To and From type to be the same, as well as checking that To and From types are trivially copyable. The static_assert version of the check is as follows:

# define BIT_CAST_STATIC_ASSERTS(TO, FROM) do {                         \
    static_assert(sizeof(TO) == sizeof(FROM));                          \             
    static_assert(std::is_trivially_copyable<TO>::value);               \
    static_assert(std::is_trivially_copyable<FROM>::value);             \
} while (false)

Effective Modern CMake

Effective Modern CMake

Getting Started

For a brief user-level introduction to CMake, watch C++ Weekly, Episode 78, Intro to CMake by Jason Turner. LLVM’s CMake Primer provides a good high-level introduction to the CMake syntax. Go read it now.

After that, watch Mathieu Ropert’s CppCon 2017 talk Using Modern CMake Patterns to Enforce a Good Modular Design (slides). It provides a thorough explanation of what modern CMake is and why it is so much better than “old school” CMake. The modular design ideas in this talk are based on the book [Large-Scale C++ Software Design](

View Perform.swift
* Perform a throwing expression, and throw a custom error in case the expression threw
* - parameter expression: The expression to execute
