Honestly as long as literals are properly converted, I don't see any other way to do this in an entirely encoding agnostic way

Depends how hard it is to work within its limits. This bug/hardware limitation creates a point of failure (someone not resetting the computer when they're supposed to)

I'm not sure if there's anything enable_if can do that concepts can't do somewhat better but yeah there's definitely a lot of subtleties that reflection is going to make nicer or possible in the first place

You already can do that with C++20 concepts and the requires expression

template <typename T>
concept has_member_foo = requires(T t) {
    t.foo();
};

// Will fail to instantiate (with nice error 
// message) if t.foo() is ill-formed
template <has_member_foo T>
void bar(T t) {
    // ...
}

// abbreviated form of above
void baz(has_member_foo auto t) {
    // ...
}

// verbose form of above
template <typename T> requires
    has_member_foo<T>
void biz(T t) {
    // ...
}

// same as above but with anonymous concept
template <typename T> requires
    requires(T t) { t.foo(); }
void bom(T t) {
    // ...
}

// If already inside a function
if constexpr (has_member_foo<T>) {
    // ...
}

// Same but with anonymous concept
if constexpr (requires(T t) { t.foo(); }) {
    // ...
}

C++26 reflection is compiletime

There's a bunch of species of cactus (family Cactaceae) but only Rhipsalis baccifera is found in the old world. Even weirder is that it's not just found in the Americas and sub-Saharan Africa but also Sri Lanka for some reason.

Map of Cactus ranges. Rhipsalis baccifera is found in Sri Lanka and sub-Saharan Africa while all other species are found in the Americas

\mathbf. It's consistent with \mathrm for well-defined constants

My uncle was a med lab tech in the hospital. They still had "no mouth pipetting" signs up in the late 90s.
