How Performance down slow it is using UFCS friendly function?

[Marcone]

// Função receive()
char[] receive(Socket socket, int size = 8192) nothrow {
	try {
		char[] buffer;
		buffer.length = size;
		int rq = socket.receive(buffer);
		return buffer[0..rq];
	} catch(Throwable){return null;}
}


s = new Socket(AddressFamily.INET, SocketType.STREAM);
writeln(s.receive(8192)); // How slow is using as friendly 
function?
