Variant can hold any type, so you can store whatever you want in the
array.  To get stuff out, though, you'll need to use .get with the
proper type, e.g.:

	Variant[] array;
	array ~= 123;
	array ~= "abc";

	int i = array[0].get!int;
	string s = array[1].get!string;

.get will throw an exception if the boxed type is not compatible with
the requested type, e.g.:

	// This will throw an Exception because array[1] doesn't hold an
	// int.
	int i = array[1].get!int;
