None Literal

None represents the absence of a value. It is valid for both nullable types (T | None) and optional types (T?):

# Nullable (C# interop)
value: str | None = None

# Optional (Sharpy-native)
x: int? = None

For T | None, bare None emits C# null. For T? (Optional[T]), bare None emits C# default, producing an empty optional. None() remains valid as an explicit alternative for T?.

See Optional Type for details on T?.

Implementation - ✅ Native - None → null for T | None, default for T?.
