fn(int, float) -> bool is a type, fn name is any top-level function's value, and a call through a local, a global, a record field, a slice element, a parameter or a result of a function type is an indirect call; two function types mix only when equal, a call checks its argument count, and a value may be null (examples/functions/values.ludic). Job.parallel_for keeps its worker check. render3d's scene is registered rather than required by name: r3d_on_draw, r3d_on_casters and r3d_on_stream_fill (hooks.ludic). The two rendering examples register theirs - and had defined scene_draw_casters with no parameter while the renderer passed one, which nothing checked. render3d declares numbers float itself; smooth.ludic is converted to floats and returns when r3d_init fails instead of running on into a segfault. Noise.* check their argument count (a call one short crashed the compiler). selfhost-build says why it failed. The migration tool reads a declared float as evidence. Seed regenerated.

**render3d takes what a frame draws as callbacks.** A program used to have to define
|
|
`scene_draw`, `scene_draw_casters` and `stream_fill` by name - a contract only the linker
|
|
enforced, whose shape nothing checked (two examples defined `scene_draw_casters` with no
|
|
parameter while the renderer passed one), and one scene per program. It registers them now:
|
|
`r3d_on_draw(fn ...)`, `r3d_on_casters(fn ...)`, `r3d_on_stream_fill(fn ...)` (hooks.ludic).
|
|
render3d also declares `numbers float` itself, so a program that imports it without the line
|
|
still gets a working renderer. The Noise functions check their argument count: a call one
|
|
short crashed the compiler, or - where it happened to fit - put fbm2's octaves in its seed.
