Hi All,

Im still experimenting with WASM and D - I really would like to 
be able to use reference types. I think I can get there with the 
metaprogramming abilities in D.

I'm trying to get the foundations right, I need a reference-like 
handle - which I've named "ptr". I'm trying to see how I can 
dispatch method calls to the underline object, I've tried 
opDispatch.

But I can't get it to fire? What am I missing?

P.S. Is it also possible to provide a way to implicitly cast from 
ptr!byte to ptr!\<a type> ?

Kind regards,
Mike Brown

incomplete `cast` I would say. You did:
```D
mixin("cast(T*)obj."~name)(vals);
```
instead of
```D
mixin("(cast(T*)obj)."~name)(vals);
```

i.e. you try to call method `test` using a pointer to void and then try 
to cast it to a pointer to T.
