I agree. At least for me it was a common pattern that by fixing a bug I've introduced another (sometimes suprising one), and by fixing that I've introduced another and so on. I would have given it up without strong editor support giving hints on the fly. (I don't remember similar experiences learning other languages even with strong static checks (e.g. haskell). Either my errors were 1 level deep there, or the propagation of errors (like changing a type somewhere) was easier to follow/predict to me)
