I had a look at your link, and this page in particular: http://epsilonwiki.free.fr/lambdaway/?view=lambdatalk%20one http://epsilonwiki.free.fr/lambdaway/?view=lambdatalk%20one If I understand well, it seems that you wrote some kind of lisp dialect with the following particularities (some of my observations might be wrong, so please correct them): - it's somehow executed in javascript, so when I load in page with lambdaway code in it, js executes the code and the output is displayed on the page - braces are replacing parenthesis - you allow unicode variables (like \Phi) - by default, an expression is a string, unless it's preceded by a colon (my first opinion is that it's not the best and it would be better to use the quotes for the strings like other languages do, but I can be wrong) I happen to be writing at the moment a blog post (it's not finished yet, but here is the beginning: http://eskatrem.github.io/Newton-Raphson http://eskatrem.github.io/Newton-Raphson ) that uses some mathematical symbols - it will also talk about lisp by the way. I guess it's something that could be - better? - done with lambdway?
