-// 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.
