Playful Programming

A C++11 technique for encoding string literals as unique types using variadic templates, constexpr functions, and preprocessor macros. The approach builds a t_string template parameterized on individual characters, uses a constexpr at() function to index string literals at compile time, and chains append template members to strip trailing null characters. The result allows inheriting from a string literal type with zero runtime overhead, at the cost of increased compile time. Note: the post itself flags this content as outdated.
