描述

Leaking disposables cat capture other objects and cause memory leaks, i.e. the common use case listeners leaking widget or react components. It would be good to have linting rule for such cases. One should consider that there can be use cases when it is not necessary, i.e. for services which are bound to the application lifetime.

研究方向
Examine existing lint rules in the Eclipse Theia repository, particularly in packages related to linting or code quality. Look at how other rules detect pattern violations (e.g., unused variables). Review the issue discussion (currently empty) and consider reaching out to maintainers for clarification on scope and acceptable false positives. Investigate TypeScript compiler API for creating custom lint rules.
