The idea came from wondering what a Lisp-like language might look like if you based it on 'everything is a table' instead of 'everything is a list'. A few old comments where this came up:

The core idea was to explore Lua's table-ness in a Lisp, with JavaScript along for the ride for browser support. I think it was an interesting experiment—interesting enough to possibly continue exploring in a more “serious” implementation, if someone were so inclined.
