Support pointer types into interfaces for extended types

[dmcgowan]

Currently pointer types are not valid for declaring extended types. This can create problems when the desired output is to set an interface value with a pointer value. To solve this problem for my case I simply made all decoding into interfaces as pointers, but I think a more general solution is needed.

Can you provide sample code that shows this problem, so I can reproduce it? It's not clear to me what you are alluding to.

Closing this as the issue is not clear to me. Please reopen when you can explain it.
