Mar 1, 2026March 2026 monthly summary for gleam-lang/gleam. Key deliverables include stabilization and expressiveness enhancements: (1) fixed a compiler crash when reading the cache for modules with large constants; (2) added constant list prepend syntax using the .. operator, updated compiler constant handling, and added tests; (3) resolved a Rust 1.94 test ambiguity by explicitly importing assert_eq in the test module; (4) implemented performance optimizations: inline constant handling in the compiler and faster single-character string prefix matching in the JavaScript (glance) path. These changes reduce crash risk, enable more expressive constants, improve test reliability across environments, and accelerate compilation and runtime string handling.
