Scala type programming resources
...unction. Indeed, type-level programming makes heavy use of implicits.
Consider this example (taken from metascala and apocalisp):
sealed trait Nat
sealed trait _0 extends Nat

The following example taken from Wikipedia:
struct C {
C() {}
C(const C&) { std::cout << "A copy was ma...
What are the differences between delegates and events?
... If course, this protection layer also prevents "clients" (code outside the defining class/struct) from invoking the delegate, and from obtaining in any way the delegate object "behind" the event.
