-            Records open a new sort of technique for late calling details from dataclasses.
-            imagine you have a dataclass called EntityIndex, which has only one field from the database: id.
-            
-            however it has custom fields, where you store a lambda expression.
-            
-            you could e.g. use it in a subquery, while still access the data.
-            however this will hit the database twice if you evaluate the iterator yourself, as the lambda is not lazy.
