Yeah I'm just talking counterfactually. At the time there were no solid cascading DSLs whatsoever, cascalog wasn't even around for another 2 years or so iirc. Cascading itself was the new hotness vs writing raw map reduce, so c.j was kind of on the edge of what was out there. The decision to keep UDFs outside of Ruby was made at the outset (out of concern for performance, and being icing on the cake, etc.) and not really revisited.
