What it does

Warns when code uses the low-level dict type.

Why is this bad?

dict erases key and value types, which makes code less type-safe and harder to understand. In most cases, map<K, V> communicates intent better and gives stronger type checking.

Example

struct State {
    data: dict
E033: low-level `dict` type should be replaced with typed `map<K, V>`
}

Use instead:

struct State {
    data: map<uint32, cell>
}
