Passing This code compiles and runs correctly.
Code
// Template engine NORTH STAR: a |template| proc reaches the INVOKING flow's
// effect handlers via `effects["each"]` (effect-kind branches, separate from
// terminal `continuations["done"]`), loops them with `{% for %}`, converts
// each `when` guard to an `if`, and calls each handler by its link. This is
// `for` minus the keyword — once green, the `~for` keyword is a thin template
// over this, and ForeachNode can die.
//
// Bodies are generated outside (as handler fns); the template holds only a
// link (`{{ h.link }}`) and emits guarded calls. No body splicing, no mixing
// of generated code into the host template — the emit-only boundary holds.
