That's right. I was thinking of the following syntax. I orginally had the idea for C++, where you can't do partial application at all.
f x y z=...

Array languages with true multidimensional arrays often have a this kind of syntax to extract subarrays, for instance A(*,J) or A(,J) to extract column J from the matrix A. Now, if you think about arrays as partial functions from indices to values, then row J of matrix A is precisely \I -> A(I,J). This syntax can be very convenient for array computations. Björn Lisper
