[go-nuts] if err != nil {print} considered harmful

Checking to see if err==nil is a very cheap operation. I think it is only a check to see if a word is equal to 0 but it definitely is at most checking two words. I'd like to see an implementation of what you suggest that is cheaper than that.

Note also that Go doesn't really do JIT optimization like some other languages do, so this is sort of out of the realm of things Go aims to do. At least as of now.
