Found by the README-wide sweep — Django/Flask/FastAPI apps' most-depended-on
lists were test and serializer methods: netbox `UserConfig.all` (3,610 from
`X.objects.all()`), `PortSerializer.create` (2,093 from `.objects.create`),
a test-local `FakeQuerySet.count` (1,910); healthchecks `AuthTestCase.get`
(880 from `Channel.objects.get()`), `ProfileAdmin.login` (702 from
`self.client.login()`); mealie `_FakeHTTPResponse.json`.
Python keeps a call through a receiver it cannot name (`User.objects.get`,
`self.client.login`, `request.POST.get`) as the bare `get` / `login`, and
exact-name matching then took any class's method by proximity. The call's
shape is now read at its column (the call's start):
- `bare` (`get(1)`): not a method — Python has no implicit self — and not a
project symbol when the file takes that name `from` a module the project
doesn't contain (`from django.shortcuts import render`);
- `chained`: only a member of what the chain names last — a method of a
class of that name (case/underscores ignored: `self.store` → `Store`,
`self.user_service` → `UserService`) or a function/class in a module of
that name (`app.helpers.slugify()` → helpers.py);
- `self.x()` / `cls.x()`, and chains split across lines: unchanged.
Fuzzy matching is case-exact for Python (`dir(…)` ≠ class `Dir`).
Lexical reachability now walks every enclosing scope, so a method of a
class declared inside a function is only reachable in there (memoized per
candidate).
A/B vs main (edge diffs, every change classified): netbox −18,091/+73
(indexes 8s → 5s), healthchecks −3,354/+361, pytest −2,950/+105,
mealie −1,802/+6, allauth −1,086/+57, DRF −943/+50, flask −167/+17,
httpx −147/+24. Gains are precise member links (`self.channel.notify` →
Channel.notify, `item.stash.get` → Stash.get, `config.cache.get` →
Cache.get, `self.provider.verify_token`); the one deliberate loss class is
calls through an instance whose type needs inference (`flask.g.setdefault`
in flask's own repo). excalidraw, typeorm, gson, okio, AutoMapper, gin and
hono byte-identical.
