My Scala take: seems cool but also like I need a Virgil to guide me through my use of the language to ensure that I do not get dragged under by Little Mysteries like so Ergo maybe not cool

Athas posted:This is archetypical scala compiler: an intended optimization which simply avoids constructing an unused error message is a breaking change, because implicit search is influenced by the state of the types in the message, and inspecting types is frequently side-effecting. this stuff is very real and hard to defend but in practice it's still a static language and every implicit resolution problem i've run into has simply caused a compilation error. in practice i'm not setting up complex implicit hierarchies that resolve in unpredictable ways. it can still happen though.

No abstractions: How to get to destination: Depressed accelerator by 30 degrees for 5 minutes. Rotate steering wheel left by 45 degrees. Hold for 6 second Rotate steering wheel right by 45 degrees. Etc etc. Good abstraction: How to get to destination: Travel straight down the road to the next junction. Turn left. Merge onto highway, keep to speed limit Exit highway via ramp. The lovely app I work in in which they think that "magic" == abstraction: Car has two buttons: shopping centre and gas station. You want to go to: airport Start mashing both buttons alternately to make car veer violently between the two destinations and hopefully hit the airport.
