I don't think so. Other compilers might not support "deriving Data", but you can always write the instance by hand.
How much boilerplate would be needed in that case? As far as I understood the web site, it would be around a line of code per data type, independently of the number of HOFs that need to iterate over the data structures - is that correct? I understand that Drift is a kind of preprocessor / code generator. Could it be used to generate the necessary boilerplate? Regards, Jo
