But the `foo[bar]` kind of construct without default pathway can happen in Rust anyway if that thing constructed dynamically (e. g. by other earlier part of arriving data).\nthis can be a common situation for some \"rules engine\" or other high-level code execution branching infrastructure.\nDoes Rust can enforce \"always have a meaningful result for `foo[bar]` construct?"}
