# StringInterpolation

The type each segment of a string literal containing interpolations
should be appended to.

```
associatedtype StringInterpolation : StringInterpolationProtocol = DefaultStringInterpolation where Self.StringLiteralType == Self.StringInterpolation.StringLiteralType
```

## Discussion

The `StringLiteralType` of an interpolation type must match the
`StringLiteralType` of the conforming type.
