Thank you for your interest in this project and your relevant remarks. About {def lis| {lambda {:x} {li :x}}}, I wrote this expression in http://epsilonwiki.free.fr/lambdaway/?view=sandbox http://epsilonwiki.free.fr/lambdaway/?view=sandbox and I didn't see any infinite loop. Click on the top-left "+" in the frameview and then on edit to inspect the code. OK, the error messages are terse, there is no syntax colorization in the textarea. There is a timeout for each keypress but it has to be improved. It's a work in progres, I'm alone and I need help.
