Hello, I am trying to using static opCall instead of the default 
constructor.

When I run it, I got "Error: need 'this' to access member A".

How to fix it?

Here is my code.

struct PriorityQueue(T) {
	static const int DEFAULT_QueueSIZE = 1;
	T[] A;
	int num;
	
	this(this){
		A = A.dup;
	}
	
	static PriorityQueue opCall() {
		
		A =  new T[DEFAULT_QueueSIZE];  // Error
		num = 1;                        // Error
		
		PriorityQueue priorityQueue;
		
		return priorityQueue;
	}
	
	bool empty() { return num == 0; }
	
	void insert( T item) {
		if( A.length == num ) A.length *= 2;
		A[ num++] = item;
	}
	
	T extractMax() {
		A.sort;
		return A[ --num];
	}
}
