// Immer 10.2 defaults to still using strict iteration (specifically
// `Reflect.ownKeys()` for symbols support). However, we assume that
// Redux users are not using symbols as state keys, so we'll override
// this to prefer `Object.keys()` instead, as it provides a ~10% speedup.
// If users do need symbol support, they can call `setUseStrictIteration(true)` themselves.
