Variants of variadic AND
summary
Implement a template that takes any number of bools and yields true only if all are true. Options shown: recursion base case and recursive constexpr functions, a noexcept trick that builds noexcept helper constructors, a partial-specialization trick that prepends and appends true and compares specializations, and C++17 fold expressions. Measurements: one argument is instant, recursion gets noticeably slower with arity, some approaches crash compilers at high arity, and fold expressions measured ~2000× slower than the fastest variant.
