Beyond += : Universal Syntax for Immutable Data Transformation
대입 연산자의 일반화로 불변 데이터 조작을 더 우아하게
Why it matters
This language design introduces a generalized approach to compound assignment operators, making immutable data transformations more readable and intuitive. By unifying custom operators like `].=` and `.=` under a single `alt` keyword, developers can elegantly express complex nested data updates without mutation, effectively bridging familiar imperative patterns with functional programming principles.
