UDP enhancement

[JS]

struct Foo
{
     @property int data() { return m_data; } // read property
     @property int data(int value) { return m_data = value; } // 
write property
     private: int m_data;
}

It would be nice if properties had an internal variable to use 
instead of having to declare it explicitly:


struct Foo
{
     @property int data() { return data.value; } // read property
     @property int data(int value) { return data.value; } // write 
property
}

This reduces code complexity. If a property does not use the 
internal variable(which I signify by .value) then it does not add 
any storage. This allows one to easily wrap fields into 
properties without having to create private fields for each 
property unless needed.
