What doesn't generalize is that the example doesn't necessarily stand for a simple one-liner, but as an example it has to be trivial, of course. But everything

What doesn't generalize is that the example doesn't necessarily stand for a simple one-liner, but as an example it has to be trivial, of course. But everything else generalizes. I took "splitting out the last 3 params" to mean "doing something very specific to the problem at hand" and extracting that isn't _always_ better.
