`visit_AsyncFor` routed to `node_contents_visit`, which only recurses into
children, so `async for` compiled with none of the guards `for` gets:
`visit_For` is what wraps the loop iterator, and the async spelling therefore
enforced less than the sync one.
Delegating to `visit_For` is not quite enough on its own. It inserts
synchronous wrappers -- `_getiter_(y)`, or
`_iter_unpack_sequence_(y, spec, _getiter_)` for a tuple target -- and both are
plain generators that `async for` cannot consume. `_use_async_iter_guards`
therefore swaps just the wrapper name for an async-capable twin:
async for a in y -> async for a in _agetiter_(y)
async for a, b in y -> async for (a, b) in _aiter_unpack_sequence_(y, spec, _getiter_)
`_agetiter_` is `budgeted_iter` over an async iterator, so an `async for` that
never yields is still stopped at the execution deadline. `_aiter_unpack_sequence_`
budgets the iteration and then applies `guarded_unpack_sequence` per element;
unpacking an element is synchronous, so the `_getiter_` handed in is the
synchronous one and is passed through untouched.
Adapted while rebuilding on `main`, worth flagging: this PR was written when
`_getiter_` was `default_guarded_getiter`. `main` now binds it to
`budgeted_iter`, which adds the per-item budget check -- so the async twins
have to carry that check too, which is why `_agetiter_` exists rather than the
async helper simply calling `_getiter_`. (This PR was opened against the
since-deleted `litellm_internal_staging`; `main` still routes
`visit_AsyncFor` to `node_contents_visit`.)
Tests: the compiled bytecode of each `async for` shape must carry an
async-capable wrapper, with the sync forms' guards asserted as preconditions;
both shapes must still run under a real async generator; and a non-sequence
element must still raise `TypeError` through the unpack guard rather than pass
silently. The guard-parity test fails with `visit_AsyncFor` put back on
`node_contents_visit` (`1 failed | 3 passed`); all 67 in the file pass here.

In total litellm runs 1000+ tests
[02/20/2025] Update:
To make it easier to contribute and map what behavior is tested,
we've started mapping the litellm directory in tests/unit
This folder can only run mock tests.
