/// ```nocompile
/// construct_runtime!(
///     pub enum Runtime with Log(interalIdent: DigestItem<SessionKey>) {
///         System: system,
///         Test: test::{default, Log(Test)},

/// The module `System: system` will expand to `System: system::{Module, Call, Storage, Event<T>, Config}`.
/// The identifier `System` is the name of the module and the lower case identifier `system` is the
/// name of the rust module for this module.
/// The module `Test: test::{default, Log(Test)}` will expand to
/// `Test: test::{Module, Call, Storage, Event<T>, Config, Log(Test)}`.
/// The module `Test2: test_with_long_module::{Module}` will expand to
/// `Test2: test_with_long_module::{Module}`.
///
/// We provide support for the following types in a module:
/// - `Module`
/// - `Call`
/// - `Storage`
/// - `Event` or `Event<T>` (if the event is generic)
/// - `Origin` or `Origin<T>` (if the origin is generic)
