void main()
{
	import std.variant, std.stdio;
	class Four { override string toString() const { return "4"; } }
	

	Variant[] anything;

	anything ~= Variant(1.0);
	anything ~= Variant(2);
	anything ~= Variant(3.0f);
	anything ~= Variant(new Four());
	
	writeln(anything);
}

You'll want to read up on std.variant.Variant to understand how
to use it. Look at get() in particular but there are other
methods that you may need depending on how you are using it.
