I have mixed feelings about this. I think anonymous functions only have a place as arguments to a function. So f(x) = x * x, doesn't look like an anonymous function but just an other way to have a named fuction. (as others have already pointed out) If we really want an alternative for the lambda expresion, I would go for the following. f = x -> x*x (or maybe we could have the λ instead of lambda) If we want haskell like patterns for defining functions I would go for the following: fac(0) -> 1 fac(n) -> n * fac(n - 1) Which seems incompatible with the proposal for an alternative lambda. -- Antoon Pardon. -- https://mail.python.org/mailman/listinfo/python-list
