Description
Description
arithmetic_side_effects uses the string representation of types to compare them. This will miss aliases (including core/alloc → std), takes longer to compare, etc.
It should use a method similar to what is done in the disallowed_types lint, where maps of DefId or PrimTy are built at lint initialization time and then used throughout the tree walk. Some type lookup code could probably even be shared (including the part where unloaded crates don't cause errors).
