A step list or a registry of fn values takes no state and still reaches every state its steps take.
The compiler now writes `reach <n> <function>` - every state a function can come to by a call, a
`fn f` it writes or a global holding fn values it reads, to a fixed point - and ludic deps reports
widest_reach beside widest_function, with how many of those states the function does not take
(Maroon Lake: app_boot, 72, all 72 through fn values). --widest N lists the N functions that take the
most states with what each reaches; --reach N orders them by reach. A baseline without widest_reach
does not hold it until rewritten.

widest_function: the most states any function or entry point of the program's own takes, with
which one; --check holds it like the other numbers and --baseline writes it.

A local bound straight from another module's global (let t =
thing_cur), or from such a local, is followed within its function, and
a write through its field or element is listed as a warning after the
counted writes. A reference from a function's result is not followed.
Reseed.

The modules of one layer use each other freely and may go round;
anything outside the layer is held to the module's uses, and a layered
module with no uses reaches nothing outside it. The cycle check walks
the graph with each layer as one node, so a cycle leaving a layer is
refused. ludic deps shows the layers and counts the largest cycle
without their own edges. Reseed.

With LUDIC_DEPS=<file> the compiler records every reference the
visibility pass resolves (from module, to module) and every assignment
to another module's global. ludic deps prints the modules,
dependencies, largest cycle, cross writes and globals written from
outside, with --graph, --dot, --writes, --uses MOD, --check FILE and
--baseline FILE. Reseed.
