Metaprogramming in C++14
summary
Uses C++14 and Boost.Hana to represent types, integers and strings as values and builds concrete examples: a parser combinator that returns tuple results, an event system keyed by compile-time strings with a runtime fallback, and dimensional-analysis quantities using compile-time integers. Implements user literals _c and _s to lift values into types, catches wrong-event and unit mismatches with static_assert, and reports benchmarks (tens of millions of triggers) showing performance close to hand-written code.
