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.

Update: perf analysis
Comparing bytecodes we can assume that append version wastes cycles in LOAD_ATTR + CALL_FUNCTION, and += version -- in BUILD_LIST. App...
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. But that means that the...
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.
