Hi, I may found an issue when trying atom functions.
In tuorial, max is for int. in code, max is defined for IntegerAtom but it doesn't work for IntegerAtom as I expected.
max
IntegerAtom

Take a look at the test. Aggregate operators work on (nested) relations.
The type checker should be complaining in your example above, however.
Oops. I misunderstood again. Thanks for the reminder.
