I think this is exactly right. I have separately used Go for more system-level code that pretty much directly wires together the standard library. Exec, x509, tar, gzip, flag, os, io, various encodings... here there is no contest. Go is a killer language for networked UNIXy stuff. These tools also compose really well, despite the absence of generics, because they speak the common language of byte arrays. Now that I think about it, Go is a language for processing byte arrays in the same way that LISP is a language for processing lists. Go is just more subtle about this specialization, and invites you to use it for other things it is less good at.
