A preview of Go version 1

I'm a little sad to see that "delete" (a pretty common word) is being used by a builtin that only works on maps and most code doesn't need. I guess it's not a reserved word, so it can still be used, but I was hoping for something a little more elegant. It seems like they would've gone with "del", to match with "cap" and "len".

Also, error.Value doesn't seem much better than os.Error. Every non-trivial program now needs to import "error"; it could almost be implicit. "error.Value" is also longer than os.Error.

Still, a pretty reasonable and good-sounding proposal over all.
