I don't want to detail the discussion, but I would love to see some of your code. I contend with this antipattern often but solve it in different ways often depending on language features. If you're doing anything other than simply calling an auxiliary method with a ton of parameters, I would appreciate seeing your solution in Javascript, a language that I'm learning but not proficient in.
