Oh yeah. Said another way, it discourages nerd-sniping, which in practice is a huge problem with functional programming and highly expressive type systems.

You end up creating these elegant abstractions that are very seductive from a programmer-as-artist perspective, but usually a distraction from just getting the work done in a good enough way.

You can tell that the creators of Go are very familiar with engineer psychology and what gets them off track. Go takes away all shiny toys.
