This is gorgeous, and I'm sure it will come in handy, thanks! I'm glad to know I'm not alone in trying this.

My particular situation is a bit different though, I need to be able to do something along the lines of:


and have it produce something like this (possibly):

SELECT * FROM mailinglists;
Listing 6.1

| mailing list name | email address          |
| ConTeXt           | ntg-context at ntg.nl     |
| Snap Framework    | snap at snapframework.com |
Output of Listing 6.1

My inspiration here is the Real World Haskell book, which ran the snippets in the book during rendering, ensuring both that the snippets actually work and that their output was faithful to the input. I don't mind having one connection as a constant.
