Simply Scala
summary
Claim: Scala itself is simple and Scala 3 reduces language surface, but ecosystem choices create complexity. Evidence: compiler has close to 100 phases, nightly tests run on more than 10 million lines of code, and a Levenshtein bug in diagnostics is fixed pragmatically. Tools and remedies: a vprofiler exposes hidden tasty-generated complexity, Scala CLI simplifies entry-level tooling, and a research+engineering effort called caprese builds a capture checker and capability types to control effects and resource lifetimes.
