Ruby types nothing, so two guesses produced most of a Ruby repo's wrong
call edges:
- `receiver.m()` through an untyped receiver took the project's one method
named `m`. It now also needs a word shared between the receiver and the
method's owner (`web_push_request.legacy_encrypt` → WebPushRequest);
`self` / `self.class` are exempt.
- a bare `m()` inside a class took any class's `m`. It now reaches only the
class's ancestry — superclasses and include/extend/prepend modules, read
from source and resolved against the lexical nesting. Calls in module
bodies and top-level blocks (specs, DSLs) are not judged.
A/B (edges removed / added): rubocop -4406/+262, mastodon -2642/+540,
jekyll -343/+10, lobsters -243/+4, sinatra -207/+2, devise -112/+3.
Deliberate losses: instance_eval'd DSL blocks inside a class method
(sinatra's own tests' `mock_app { get '/' }`), and helpers on a framework
class the repo reopens past an external superclass (devise setup_mailer).
