is there any reason UFCS can't be used with 'new'?

The following code works perfectly fine. The precedence of the 
`new` operator was changed in a release a year or two ago.

class Button
{
	typeof(this) text(string t)
	{
		return this;
	}
	
	typeof(this) textColour(int c)
	{
		return this;
	}
}

void main()
{
	auto b = new Button()
                     .text("Hello, world!")
                     .textColour(0xFF000000);
}
