/** @defgroup hide
 * SigC::hide() alters a Slot in that it adds one or two parameters
 * whose values are ignored on invocation of the Slot.
 * Thus you can discard one or more of the arguments of a Signal.
 * You have to specify the type of the parameters to ignore as
 * template arguments as in
 * @code
 * SigC::Slot1<void, int> slot1;
 * SigC::Slot0<void> slot2 = SigC::hide<int>(slot1);
 * @endcode
 *
 * SigC::hide_return() alters the Slot by
 * dropping its return value, thus converting it to a void Slot.
 *
 * Simple sample usage:
 *
 * @code
 * int f(int);
 * SigC::Slot1<void, int> s = SigC::hide_return( slot(&f) );
 * @endcode
