   Not fully thought through, but you could maybe do something like
   
   ```
   struct Decimal128Type {}
   struct Decimal256Type {}
   
   trait DecimalType {
     ...
   }
   
   impl DecimalType for Decimal128Type {}
   impl DecimalType for Decimal256Type {}
   
   struct GenericDecimalArray<T: DecimalType> {}
   ```
