Any Go developers with past experience in "heavier" frameworks have thoughts on giving it a try?

I enjoy working with "batteries included" frameworks currently, and value the approach of "Here's an ORM... here's a template language... here's an auth system... use or remove them as you see fit"

I've been told that the Go standard library is fully-featured enough that it can be considered a framework in its own right, but I haven't heard how converts from the Django/Rails world feel about the completeness of that "framework"
