So, is there some way to store a reference to a D class
instance in that 'user_data' field?
Should be ok to cast the reference itself to that type - don't
take the address of it, since that would be the address of a
local, but just cast it:
MyObject foo = new MyObject();
c_struct.user_data = cast(intptr_t) foo;
And when you get it back:
foo = cast(MyObject) c_struct.user_data;
In D, MyObject is already basically a MyObject*, so if you did
&foo, the type would be more like MyObject** which is probably
why you didn't have luck doing it before.
