I think you're interpreting that sentence a bit too literally. Clearly the developers of Go are interested in very carefully balancing language features with language complexity (seemingly both for language users and language implementers). And it is in that sense that they probably mean solve in the best way possible, namely to solve a problem in the best way possible with those two concerns - complexity, "expressitivity" - carefully balanced[1]. [1] Though one can argue that the word "best" seems inappropriate when the concern is a very subjective balancing act.
