I don't see any new semantics in M-expressions, but maybe it's me. >From the examples listed: (car lst) => car[lst] (car (append lst1 lst2)) => car[append[lst1; lst2]] Say you want to drop the ";" for argument separation (it's syntactic sugar after all), and say you want to use parens instead of brackets: car(append(lst1 lst2)) > > So it should be possible to easily switch between these two > representations. > > But thats only an idea, I'm not sure if it's really feasible. Switching can be maybe easy, but you lose quite some power: as Pascal said in the other post, code won't be data anymore, and it's not only a matter of evaluating code at runtime. __ Alessandro
