Show HN: Combinators in Array Languages
Summary
Show HN: Combinators in Array Languages introduces the Sage Bird, a fixed-point combinator in the eager array language sw-MLPL. It explains how to implement recursion without naming functions by using a named partial (an applicative Sage) to avoid divergence in an eager evaluator, contrasts with lazy Y combinator approaches, and demonstrates runnable factorial and fibonacci examples. The post also surveys how the APL lineage handles recursion and provides runnable demos and repo references.
