Can I list-initialize a vector of move-only type?
... rather the underlying elements themselves might be const, which cannot be cast away in a well-formed program.

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...

How do I initialize a TypeScript object with a JSON object
...the type map:
export function fromJson(json: string): Person {
return cast(JSON.parse(json), object("Person"));

I've left out some code, but you can try quicktype for the details.
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.

What new capabilities do user-defined literals add to C++?
...ould have if these have been added to the language itself. We can even add cast operators (which is usually a bad idea, but sometimes, it's just the right solution).
We still missed one thing to have user-types behave as built-in types: user-defined literals.
So, I guess it's a natural evolution for...

std::vector versus std::array in C++
...ding the pointer from the user of the class (in C++, arrays are implicitly cast as pointers, often to dismaying effect). The std::array<T> class also stores its size (length), which can be very useful.

What is a lambda expression in C++11?
...a, it looks for a type conversion which allows it, which includes implicit-cast-to-function-pointer, and then calls that! Sneaky!

When to use actors instead of messaging solutions such as WebSphere MQ or Tibco Rendezvous?
...no-brainer. However Akka's Java bindings are not very Java-ish and require casting due to Scala's type system.
Also in Java people don't typically make immutable objects which I recommend you do for messaging. Consequently its very easy in Java to accidentally do something using Akka that will not...
