> It's generally the opinion of the Go community that map, reduce and filter are bad ideas due to how easily they are abused.

There is a germ of truth here - sometimes list comprehensions make code harder to understand than if you just wrote an if statement or a loop - but you've overgeneralized. I don't think anyone on the core Go team seriously thinks that map and reduce are bad ideas when Google relies so heavily on MapReduce (and its successors).
