/* KSVarArgs is a set of macros designed to make dealing with variable arguments
 * easier in Objective-C. All macros assume that the varargs list contains only
 * objective-c objects or object-like structures (assignable to type id).
 *
 * The base macro ksva_iterate_list() iterates over the variable arguments,
 * invoking a block for each argument, until it encounters a terminating nil.
 *
 * The other macros are for convenience when converting to common collections.
