I was being tongue in cheek on that one, sorry if it didn&#x27;t come across that way. Although I&#x27;ve been a Rails dev for 6 years now, I&#x27;ve come to hate the TDD approach and am a convert of FP and types, &amp; compilers a la Haskell. Because there really is no such thing as a massive change in FP IMO. Unfortunately I&#x27;m not competent enough in it yet so Rails still pays the bills.
