This is a very neat option for loops. If you need to loop through a list of field values you can use the
FieldValueList mask. This could replace using the combination of
Peek. That is assuming you only need to loop through the distinct list of values.
Notice the difference how the two options handle the value Two.
FieldValueList (Blue) uses the symbol table, so it loops over the unique values, whereas
Peek (Red) loops over the rows of the internal table.
