Embedding external types

How do you feel about adding some functions, for example ```func Embed(exteranTypeInstance any)``` to reuse external type definitions with their methods? I want to use methods of go types from external libs. I found a solution with "ConvertTo()", but in my opinion it is too inconveniently to write every time something like res.ConvertToMyCustomExternalType().MyMethod().

Or is there any other way to make it possible to use res.MyMethod() directly?
