# redundant-forwarding-function

Discourage functions that only forward their parameters unchanged

A function whose complete body calls another callable with the same parameters adds a name without adding behavior.
Instead, you SHOULD use the underlying callable directly.

Exported aliases, overrides, decorated functions, and ambient declarations remain intentional boundaries.
