Standard struct constructors for the heap?

[bearophile]

Regarding the efforts of removing limitations from D, do you know 
if there are problems in implementing this oldish enhancement 
request?

http://d.puremagic.com/issues/show_bug.cgi?id=4086
The idea is to just allow the heap creation of simple structs 
with no need to define a constructor:


struct Node {
    int data;
    Node* next;
}
void main() {
    Node n1 = Node(10); // OK
    Node n2 = Node(10, null); // OK
}


I am writing many of those stupid struct initializations, it's 
boring busy work and they don't make the code more readable, just 
longer, so I'd like D to define them by itself:

this(int data_=int.init, Node* next_=(Node*).init)
pure nothrow @safe {
    this.data = data_;
    this.next = next_;
}

Removing this limit also makes D more uniform with 
locally-allocated struct construction semantics.
