Description (last modified by exarkun)
If a Deferred goes out of scope without being returned (or passed into a method that is intended to consume it such as deferredutil.eventual_chain), that's usually a bug. Write a static analysis using compiler.ast to catch such bugs.

Intriguing but probably not. Static analysis of Python is really hard. Such a tool would likely produce false positives and be annoying. Instead, have comprehensive unit test coverage.
