(ctx interpreter.Activation)

// Eval evaluates the left-hand side optional to determine whether it contains a value, else
// proceeds with the right-hand side evaluation.
func (opt *evalOptionalOr) Eval(ctx interpreter.Activation) ref.Val {
	return opt.Exec(interpreter.AsFrame(ctx))
}

// evalOptionalOrValue selects between an optional or a concrete value. If the optional has a value,
// its value is returned, otherwise the alternative value expression is evaluated and returned.
