I'm curious as to what prior languages were used as foundations for GO. For example, I really liked Digital's Bliss language for low level operating system hacking. Like GO, it was utterly consistent. Sadly, unlike GO, it has a lot of syntactic cruft that make it look forbidding.
In Bliss, you could do anything. I thought that its syntax and power was greatly superior to C, but of course C took over the world.
