I'm not sure I agree. A lot of camlistore's idioms don't feel like "normal", idiomatic Go. Since it was still being written while the standard library and language was evolving, I get the feeling when reading the code that it's more like doing archeology of the Go language.
IIRC it also still has a non-standard build process (go run make.go) for the same reason (it was being written while the library/language were in their infancy).
Many of what is now the Go standard lib came from Brad Fitzpatrick's work on Camlistore.
