Use cases

• Optional/nullable data types.
• Variant data types.
• Flag with extra information needed only in some cases (or different in different cases).
• Modeling states in a state machine where each state can have some data associated with it.
• List of operations for batch processing, where each operation can have its own arguments.
• Alternative to function overloading that allows avoiding combinatorial explosion when there are multiple parameters that need variants.
• Nested data structures with heterogenous nodes.
