Enso story continued in 2024 as well...

Performance and Runtime

• Magnitudes of startup speed up by using GraalVM AOT compilation
  • Register all polyglot java import classes for refective access and co.
• Avoid IR traversal by converting (some of) our Passes to mini passes - lowers GC presure, improves locality, allows inlining
• adopting Apache Arrow format for interop with Python Pandas & co.
• 5-10% speedup...
• Eliminate 10% overhead ... by inlining objects together
• Modularization and cleanup of dependencies like Removing Truffle API dependency from runtime-compiler project
• Never ending rewriting from Scala to Java like #9810
• Use small JDK by Reduce set of JDK modules required by Enso
  • Removal of Desktop and Java SE modules not needed in a headless application like Enso
• Talking to compiler to benchmark ArrowOperationPlus node and speed it up!

Tooling and other Projects

• Enso language support with parser in VSCode, IGV, etc.
• Instrumentation, visualization and autoscoped constructors
• Contributed to Snakeyaml

Improving Language & Libraries

• Autoscoping of constructors - essential and speculative language improvement
  • Merged as #9190
• Binary operator resolution based on that value - technically double dispatch at full speed
• Equality and Conversions
• Intersection types & type checks - towards inheritance with functional programming flavor!
• Fixing Inconsistent import and FQN behavior
• Reworked comparable & hashing & equality and make it consistent and sound

List of 257 issues and requests resolved in 2024. The story continued in Enso2025. The previous year was Enso2023.
