-- Polyglot task fan-out: one Lua script spawns a tiny task on FIVE different
-- engines (JavaScript, Squirrel, Berry, Scheme/s7, Wren). Each child prints a
-- one-line hello in its own language through the shared calogPrint native, so a
-- single run shows all five runtimes executing side by side under one broker.
-- The Scheme child is wrapped in (begin ...) because s7 evaluates one form; the
-- Wren child reaches natives via Calog.call. A short timer lets every child run
-- before we tear down and exit.
-- Run: bin/calog examples/scripts/polyglot/taskFanout.lua

-- Each entry pairs a taskSpawn engine name with a minimal, idiomatic snippet.
