But depending on the topic it's an absolute nuclear weapon. I've seen people accumulate pages of imperative code. Side effects everywhere, no reuse of small logical bits. 80% waste, averaging 4-6h per bugfix.
On the other hand short immutable code is more readable (yes even with a single letter vars), is linearly ordered, and often reusing the same combinators.
