I assume you're referring to cgo. I honestly don't see how that's 
any easier than using dpp. It's been quite a few years now, but 
cgo was what attracted me to an otherwise bland language - I 
thought it would make it easy to solve my problems. cgo has its 
limitations (or maybe they are limitations of the language 
itself, I'm not sure). My recollection is that I gave up after a 
painful attempt trying to pass function pointers. Some 
limitations are listed here: https://golang.org/cmd/cgo/ For 
instance, "Go struct types are not supported; use a C struct 
type. Go array types are not supported; use a C pointer."

Overall the experience wasn't what I had hoped. Just to be clear, 
I'll repeat that I haven't used Go in ages, but "simple, straight 
import and you are done" was not my experience when I used cgo.
