# removeMany

Remove multiple keys from the Trie.

## Signatures

```ts
export declare const removeMany: {
    (keys: Iterable<string>): <V, E, R>(ref: RefTrie<V, E, R>) => Effect.Effect<Trie.Trie<V>, E, R>;
    <V, E, R>(ref: RefTrie<V, E, R>, keys: Iterable<string>): Effect.Effect<Trie.Trie<V>, E, R>;
};
```

## Why

Applies remove many to the committed trie value and publishes only the result, preserving its
element order and equality rules.

## Ownership and lifetime

Running remove many performs one serialized trie transition and resolves with its committed
value. It acquires no resource; failures and services remain those of the source ref.
