A programming technique where templates are used to generate code at compile time, essentially writing programs that write programs.
Combines 'template' (C++ feature from 1990s) with 'metaprogramming' (programs about programs, 1960s). This technique emerged accidentally when C++ developers discovered templates were Turing-complete and could perform computations during compilation.
C++ templates accidentally became a full programming language that runs during compilation - developers discovered they could write programs that generate other programs, like having a robot that builds other robots based on blueprints you give it!
