Research direction

Examine the current implementation of @deprecate in base/deprecated.jl to understand why it fails across modules. Analyze how the macro resolves function names and consider modifications to support qualified module paths. Review the single comment on the issue for additional context. Check if the feature has been addressed in later Julia versions or related pull requests.
