Class Initialization

[Zachary Lund]

In C++, they provide a mechanism to initialize class variables to a 
passed value.

class Test
{
	int bob;

public:
	Test(int jessica) : bob(jessica) { }
};

The above basically says "int this.bob = jessica;" as opposed to this:

class Test
{
	int bob;
public:
	Test(int jessica) { bob = jessica; }
};

which basically says "int this.bob = void; bob = jessica;". Now, I'm not 
a speed freak but this is a quick and should be a painless optimization. 
D allows defaults set by the class but cannot seem to find anything to 
allow me variable initialization values. Not that it's that big of a 
deal but am I missing something?
