template<class R, class...Args>
auto Y = [] (auto f) {
auto action = [=] (auto action) -> std::function<R(Args...)> {
return [=] (Args&&... args)->R {
return f( action(action), std::forward<Args>(args)... );
};
};
return action(action);
};
Some fun C++ stuff I've done round here:
- A: Convert a run-time value or type to a compile-time value, also works with lists of types.
- A: Named operators, does what it says on the tin
- A: can_apply, a useful trick that helps make traits like "can serialize" or "can convert to string".
- A: task, a move-only implementation of
std::function. - Q: Function curry, that does partial binds and the like.
- A: Me playing around with hana-like metaprogramming, together with the idea that template work best if everything (including templates) is a type. Here is some evil operator abuse, where I manipulate types with
+. - A:
std::functionthat returns vectors of its own type.
Here is a neat question I didn't ask:
the answer seems to be "actually, nope, but nobody noticed".
