# subscript(_:)

Subscript that shadows the standard Dictionary subscript to provide path-based access. When the key contains ":", it is treated as a path with ":" as the delimiter; otherwise the regular dictionary key semantics apply.

## Declaration

```swift
subscript(key: String) -> USDValue? { get set }
```
