Well actually, people with bizarre build requirements are starting to use clean Go source code as a build target of their increasingly diverse preprocessors. Can't be healthy.
I use Go and I don't see any particular expressivity or ability to code easier/faster, compared to, say Python.
The benefits are: type checking (if you need it), more speed (but not as much as advertised), and easy concurrency (if you need it).
I think one of the main "marketing" points of Go, in a grassroots way, is that some people coming from Python/Ruby/js etc, that have never (or only very lghtly) used C/C++ before, feel suddenly like they are using a "hard, grown up's language", what with pointers and everything. It's mostly an illusion, though.
