   The parser also does typechecking, and attempts to cover a good subset of DML, DDL and procedural SQL as well. Maybe it could be smaller! How would you handle correlated subqueries when converting from SQL to RA?

   That is really fascinating, I will have a good look at that, thanks! I have a SQL parser in Haskell on github here (using Parsec): https://github.com/JakeWheat/hssqlppp The model in the article is roughly based on the

   We have one other Haskell programmer, who previously worked with some other functional programming languages (mainly some dialect of ML I think) and was working with Erlang in his previous job, and he picked it up quite easily. I think he i
