# Parser.OrElseWith

Binds a fallback Parser for later composition.

## Signatures

```ts
interface OrElseWith<Q extends Any> extends TypeFunction {
    readonly return: InputOf<this> extends infer P extends Any ? OrElse<P, Q> : never;
}
```

## Why

Reusable alternatives preserve the original-input fallback rule.

## Ownership and lifetime

TypeScript instantiates `OrElseWith` while parsing a string-literal input; partial results and unconsumed text exist only in the resulting type.

## Property: return

Computes this type lambda's parse result for its current input.

## Property: return: Why

The local type-function protocol evaluates each parser combinator through this member without a parallel runtime object.

## Property: return: Ownership and lifetime

TypeScript evaluates `OrElseWith.return` when the surrounding parser is applied; the associated result is erased and retains no input at runtime.
