Often the federation explores interesting things. A while back I remember seeing a lisp implementation in javascript. I didn't have enough time to explore when I first saw it and it slipped from memory. This weekend lambdatalk resurfaced when I had some time to explore. Here I begin sketching an integration with wiki. lambdatalk 
I began experimenting first with help from Beaker. I frequently start there, inspired as I am by Javascript without Pipelines. No persistence yet, but I was able to install lambdatalk into my own web page:

If you happen to be running Beaker you can also use the DAT url: [dat://beaker-lambdatalk-experiment.hashbase.io/](dat://beaker-lambdatalk-experiment.hashbase.io/)
