Subject: delayed initialization with alloc_function


Hello guys, I am wrapping a C++ library and after changing from define 
singleton method "new" to alloc function and initialize, I ran into this 
problem, imagine the classes are like those:

class MyOtherClass
{
public:
��������MyOtherClass(int a, int b);�����
private:
��������int a;
��������int b;
}

class MyClass
{
public:
��������MyClass(int a, int b);
��������MyOtherClass myFunc(int c);
private:
��������int a;
��������int b;
};

1.- in alloc function, I have to create a MyClass object and wrap it with 
Data_Wrap_Struct, but I cant create an object at that time, because I have no 
constructor parameter until initialize (and I dont have a default constructor 
either). How do I solve this?
2.- If class MyClass func returns a MyOther class object, whats the best way 
to wrap this?, I have even a function that returns a collection of 
MyOtherClass objects, so I think I have to iterate trough it, and create a 
ruby wrapped object not from scratch but wrapping the current object in the 
collection, and then add all the ruby objects to a Ruby array, in this case, 
whats the best way to wrap it?

Thanks for the help guys!
