Simplify OnTerminate.
No, not "awful", AWFUN!
Speaking of AWFUN, here is an alternative implementation of it:
#define AWFUN(t, f) cond_fun<t, f##A, f##W>
template <typename T, auto F, auto G>
std::enable_if_t<std::is_same_v<T, char>, decltype(F)> cond_fun = F;
template <auto F, auto G>
auto cond_fun<wchar_t, F, G> = G;
This implementation uses a variable template instead of a function
template, but I decided against it, as (at least I think) it would
instantiate useless variables that merely point to pre-existing API
functions. Like,
auto cond_fun__wchar_t__blablabla = MessageBoxW;
auto cond_fun__char__blablabla = MessageBoxA;
which is quite useless. Better to just have a constexpr function,
which the compiler may inline, return the real function pointer.
