-Since LINQ queries use deferred execution, returning `query` will actually return the expression tree representing the above query. Each time the caller evaluates this result using a `foreach` cycle or similar, the entire query is re-executed resulting in new instances of `GoldMember` every time. Consequently, you cannot use the `==` operator to compare multiple `GoldMember` instances. Instead, always explicitly evaluate the result of a LINQ query using `ToList()`, `ToArray()` or similar methods.
