/**
 * {@linkplain Parameter}s are *not* about to find/identify the {@link Constructor} to use! This
 * would get far to complex to understand (yet simple to implement) using different constructors
 * depending on the {@linkplain Parameter}s.
 * 
 * {@linkplain Parameter}s identify the {@link Instance} to use for the constructor.
 * 
 * How {@linkplain Parameter}s are understood:
 * 
 * A {@link Class} (via Type)
 * Use the default instance of the given {@linkplain Class}
 * A {@link Type}
 * Use the default instance of the given {@linkplain Type} (needed for generic classes)
 * An {@link Instance}
 * Use the instance identified by the given {@linkplain Instance}
 * A {@link Dependency}
 * Use the instance resolved by the given {@linkplain Dependency} (finest level of control)
 * An instance {@link Object}
 * Use the given {@linkplain Object} (for the first parameter it is assignable to)
 *
