The original lambda calculus also didn't have implicit currying for multi-variable functions. If you wanted to curry a function you had to write out λx.λy.

The original lambda calculus also didn't have implicit currying for multi-variable functions. If you wanted to curry a function you had to write out λx.λy.λz. x (y z) If you wrote the much more user friendly λ x y z . x (y z) And tried currying it then it would fail. The author is complaining that Python doesn't use a dialect of lambda functions used in Haskell. Which is true. Python isn't Haskell and shouldn't be.
