Using smart pointers for class members
...t a client from moving (unless the client is a mad scientist keen on const_casts), I personally wouldn't do it. It exposes an implementation detail, i.e. the fact that ownership is unique and realized through a unique_ptr. I see things this way: if you want/need to pass/return ownership, pass/return...
When is an interface with a default method initialized?
...p->local_interfaces()->at(i);
InstanceKlass* ik = InstanceKlass::cast(iface);
if (ik->has_default_methods() && ik->should_be_initialized()) {
ik->initialize(THREAD);
....
}
}

So this initialization has been implemented explicitly as a new Step 7.5. T...

What is the fastest integer division supporting division by zero no matter what the result is?
...
Awesome. Can be made constexpr and avoid needless type casts like this: template<typename T, typename U> constexpr auto fdiv( T t, U u ) -> decltype(t/(u+!u)) { return t/(u+!u); } And if you want 255, (lhs)/(rhs+!rhs) & -!rhs

Is a `=default` move constructor equivalent to a member-wise move constructor?
...as rvalue reference type T&&, it is direct-initialized with static_cast(x.m);
otherwise, the base or member is direct-initialized with the corresponding base or member of x.
Virtual base class subobjects shall be initialized only once by the
implicitly-defined copy/move construct...
Reference: Comparing PHP's print and echo
...print. print e, when evaluated:
evaluates its single argument e and type-casts the resulting value to a string s. (Thus, print e is equivalent to print (string) e.)
Streams the string s to the output buffer (which eventually will be streamed to the standard output).
Evaluates to the integer 1.

How do I initialize a TypeScript object with a JSON object

export function fromJson(json: string): Person {
