BTW how does it rely on having everything on the D side? Maybe 
it's enough to have just instance size and method symbols? But 
then there's problem with this inference: what if the type is 
intended to be used as a reference type and you infer it to be 
POD, and it can also flicker between POD and non-POD depending on 
defines.
