Description

Now that the effect system supports affine effects, it would be nice to update some standard library interfaces (e.g., Mutable) to actually use this feature.

Contributor guide

Research direction
Review the current Mutable interface in the standard library and understand how affine effects work in the effect system. Then propose updating the interface to use affine effects, ensuring backward compatibility.
