Detailed Description

The Operand class corresponds to the operand nonterminal in the MessageFormat 2 grammar, https://github.com/unicode-org/message-format-wg/blob/main/spec/message.abnf .

It represents a Literal | VariableRef – see the operand? field of the FunctionRef interface defined at: https://github.com/unicode-org/message-format-wg/blob/main/spec/data-model.md#expressions with the difference that it can also represent a null operand (the absent operand in an annotation with no operand).

Operand is immutable and is copyable and movable.
