No, TFA is mostly about making errors consistent in a large application, while exception (vs error as standard return value) is largely about easier bubbling, which is one thing TFA hardly talked about (maybe I missed it, I only skimmed the article). In fact it spends a lot of energy on wrapping which is the opposite of automatic bubbling provided by exceptions by default. Throwing random, inconsistent module/package/whatever-specific exceptions from everywhere causes most of the same problems described in TFA.

I feel like all the canned comments saying TFA is about implementing exceptions / ADT result type are from people who didn’t read the article and just want to repeat all the cliche on the topic (for easy karma? No idea what’s the point).
