027's 4f-4: loops nested to any depth: the load counts a module's deepest nesting (nesting), a run keeping PURE_MODULE_NESTING (8) on its stack as before and a module nesting deeper running in the executor that calls, its loops in its app's room (PureApp.deep, grown to it), so run()'s hot path is as it was; the JIT compiles modules nesting 8 at most; a function's nesting counted without a cap (u32), its frame sized to it; unit test: 40 loops nested, run to their end (2^20 rounds) and stopped by the work budget (2^40), 8 still on the stack; counts: b42 against b41 with batches BFS -0.12%, without BFS +0.09%, the rest within 0.001%; the bank's queries (s41 and s42 in turns, six each) in_credit +1.04%, per_branch +0.60%, ranks +0.36%, the rest within 0.01% (their spread: the bank has no functions, so none runs the changed executor, and s42's in_credit is within s41's own earlier six); 008 and 027
