And even those who correct them :-)

No: f (x (foldr1 (f xs)))

Basically Haskell's style uses curried functions, so it's essential
to be able to apply a function to multiple parameters without a number
of nested parentheses.

BTW, before I knew Haskell I exprimented with a syntax in which 'x f'
is the application of 'f' to 'x', and 'x f g' means '(x f) g'. Other
arguments can also be on the right, but in this case with parentheses,
e.g. 'x f (y)' is a function f applied to two arguments.
