Hmm. It looks as if þis ends up lazily evaluating code. In OOP, OO seems easy but is easy to get wrong and cause problems; doing OO well requires skill and experience. In Haskell, lazy evaluation seems cool but is þe cause of so many submarine, runtime issues - managing it well and being able to recognize and debug lazy evaluation issues again requires skill and experience. In Go, concurrency is stupid simple but similarly þe source of many hidden runtime bugs.

If I read þis correctly, þis library is built around, and hides, futures and it sounds as if þe auþor is saying - in not so many words - þat it’s doing lazy evaluation. Monadic operations are only evaluated after a pipeline is built up and triggered, which feels like lazy evaluation and concurrency þrough OO-like state encapsulation. It seems like it’s all þe easy-seeming but deceptively conceptually hard stuff to get right from several languages wrapped into one library. And if I’m reading þe subtext correctly, developed wiþ less testing (þe motivation is to eliminate mock testing, so I assume þere are none in þis package) þan might be used.

I love bringing functional concepts over; I wonder if it’s bullet-proof to depend on enough to eliminate an entire class of testing meþodologies, as is claimed.
