Calling code w/o headers...
summary
Shows a concrete way to call a function from a library header you do not have at compile time by exploiting delayed template instantiation and ADL: declare a template that defers the call, then add a tiny namespace monorail helper that forces argument deduction so lookup finds MonorailHash regardless of include order. Tests reveal MSVC accepts the naive variant but Clang/GCC need the helper; the hack works across include orders and avoids changing callers.
