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.

Honestly I feel like Shadow is an IEM guy so he can feel superior to others

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

Honestly I think the fame of the tank man has overshadowed other scenes of the incident and people often don't realize just how bloody it was.

CW blood and shooting

It's gotta be the companies. Since the British forced out the Indigenous population in the 70s the only permanent inhabitants of the Cagos Islands/BIOT have been US military personnel.

Unbeweevible!

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

Organisms need some oxidizing agent to respire. We use oxygen because it's very highly reactive and thanks to photosynthesis is goddamn everywhere.

in my defence, am sleeby ouppy 😌

Better than asking a dentist is asking a dental hygienist. Dentists are dental surgeons primarily concerned with solving specific problems with surgical intervention. Hygienists are oral health nurses concerned with preventive care and overall health and wellbeing.

And listen to your hygienist. There is no cure-all toothpaste for everyone (eg not everyone needs anti-sensitivity toothpaste, the risk of erosion in whitening toothpastes might be a concern for some people, some people need higher fluoride concentrations, etc)

If it's fluoride free then it doesn't do much. Get toothpaste with actual medicinal ingredients

When avoirdupois pounds and pounds-force are used together I'm pretty sure it's more common to use 'lb' for avoirdupois pounds and 'lbf' for pounds-force.

Maximum is 100 °F and minimum is 95 °F. Those seem pretty arbitrary to me
