Description
This is a new lint suggestion - which I don't know if is possible - based on ADA's in_out parameter property.
In a function, catch any &mut parameter which is never read, suggesting to move it as/into the return type.

Research direction
The issue proposes a new Clippy lint for &mut parameters that are never read, based on Ada's in_out parameter property. Start by reviewing existing Clippy lint implementations and their tests; done means the lint reliably identifies the described parameters and suggests moving them into the return type.
