Dans ces cas, vous pouvez utiliser la technique Python "d'affection par décomposition" (appelé _unpacking_ en anglais) d'un `dict` avec `**dict_to_unpack` :

```Python
old_dict = {
    "old key": "old value",
    "second old key": "second old value",
}

Most source code targets the daemon and the remaining code either targets a single runtime, for example the Gradle client, or is shared across multiple runtimes.

## Composition by architecture modules

Each [architecture module and platform](platforms.md) can contribute code to any of the runtimes.
Not every module contributes to every runtime.

The core-runtime module defines each runtime:

The project state is managed by the `ProjectState` class.
It is created for each project in the build definition, once per build execution and is discarded at the end of the execution.

Each [architecture module and platform](platforms.md) can contribute code to any of the elements.
Not every module contributes to every element.
