why {} instead of ()? Because we are in a wiki context where text is 95% of the content. I want to be able to write (Hello World) without triggering any evaluation, trying to apply Hello to World. Usually, other languages (except HTML) evaluate every words in code except quoted sentences - called strings - like this "Hello World". Lambdatalk inverts this process: everything is unevaluated out of curly braces. For instance this expression 1+2 is equal to {+ 1 2} should be written in Javascript like this: "1+2 is equal to " + (1+2). I think that it's the main point of lambdatalk, this inverted process. You could have a look to these links: "curl | latex | LML | PDF | skribe | SXML" in the page http://epsilonwiki.free.fr/lambdaway/?view=curl.
