Does D has built-in stack structure?

AFAIK there's no built-in, but std.array.Appender could be easily 
wrapped in an interface that makes thinking of it as stack easier:

struct Stack(T)
{
	import std.array: Appender, appender;
	Appender!(T[]) _app;
	@property ref inout(T) top() inout { return _app.data[$ - 1]; };
	@property bool empty() const { return _app.data.length == 0; }
	void pop() { _app.shrinkTo(_app.data.length - 1); }
	void push(T t) { _app.put(t); }
}
