Conveniently Declaring Compile-Time Strings in C++
...s a literal string and compiles the contents to a function. See the answer by dyp. A very complete-looking library is metaparse. Essentially, you can define any mapping from literal strings to types, and implement it with this kind of technology.

@naive231 by "see" I meant see functions so you can break at them, not the source: you have to hit run for that so that dynamic libraries get loaded. For source, google it and find: stackoverflow.com/questions/10000335/… :-)

Why does the C# compiler not fault code where a static method calls an instance method?
...he explanation of the dynamic example of the Original Question is that, in order to be consistent, when types are dynamic we also first find the best overload (checking only parameter number and parameter types etc., not static vs. non-static), and only then check for static.

What is the fastest/most efficient way to find the highest set bit (msb) in an integer in C?
...e transparent to everyone, but when you realize that the code shifts right by one bit repeatedly until the leftmost bit has been shifted off (note that C treats any non-zero value as true) and returns the number of shifts, it makes perfect sense. It also means that it works even when more than one b...
