It's worth mentioning that the author of this tool is Brad Fitzpatrick, one of the main contributors to the Go standard library and, in my opinion, the most "entrenched" Go developer on the team. And by that I mean he uses Go to build large and practical projects on his own (See Camlistore), so he knows what the language feels like from a perspective similar to the rest of us. He's also one of the only advocates on the team for the inclusion of generics.
