Yes, it is already included in the .gitignore file. I guess I meant it's not special to _Racket_, but it is useful to have a convention for stuff like git and helping others. :) Jay On Tue, Jun 23, 2015 at 11:30 PM, Matthew Butterick wrote: > PS The 'extra-pkgs' directory is a tiny bit special:

I ran into this issue recently. The right answer for me was to write a trampolining macro. define-values is treated specially by the macro expander and thus can't be handled easily in a local expand.

Yes, that should be fine. One note about your sample code: the isolation mode of inner transactions must be #f (the default); you can't change isolation levels once you've started an outer transaction. Also keep in mind that nested transactions are not supported for ODBC connections. Ryan On
