From 9036ce3400f3dbef1fc6d481ff929bf66a9b037b Mon Sep 17 00:00:00 2001 From: giles Date: Thu, 28 May 2026 02:45:36 +0000 Subject: [PATCH] =?UTF-8?q?go:=20Phase=209=20closed=20=E2=80=94=2012=20end?= =?UTF-8?q?-to-end=20programs,=20total=20609/609=20[nothing]?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit 12 canonical Go programs running through the full pipeline (lex + parse + types + eval + sched + stdlib): sieve-of-Eratosthenes via boolean slice (modulo-free), linear search, slice reverse, fib(10), sum-of-squares via generic Map+Reduce, word-freq counter, channel pipeline (gen→sq→sum), worker pool, bubble sort, sentence-reverse, Filter+len, Ackermann, defer+recover on div-by-zero. Each test threads ONE self-contained Go program through go-eval- program. The v0 limitations chiselled in earlier phases (float division, sync spawn, type erasure, nil-as-unbound) are now durable as commit-trail artifacts; e2e variants written to avoid them where possible. HTTP-ish ping-pong + WaitGroup deferred (real preemption + sync package needed).
