From 76f7e3b68a436ebaeaa15e45ebfc17e14a3f7755 Mon Sep 17 00:00:00 2001 From: giles Date: Thu, 16 Apr 2026 21:33:55 +0000 Subject: [PATCH] HS: return/guard, repeat while/until, if-then fix, script extraction MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Parser: if-then consumes 'then' keyword before parsing then-body. Compiler: return→raise, def→guard, repeat while/until dispatch. Runtime: hs-repeat-while, hs-repeat-until. Test gen: script block extraction for def functions. repeat suite: 10→13/30.
