It is as you fear: Go does not have a unified syntax for looping over
either builtin containers or user containers. In Go this rarely comes
up due to the absence of generics.

I might object to the use of "rarely" here: there's no convenient construct in Go to iterate over any non-fixed container but a channel, and while you can make an iterator/generator out of a channel, it is awkward and fraught with peril because of some of the peculiarities around hanging channels. This comes up rather a lot for me, actually.
