Completely central in that the type of functions *is* a curried type
(in the *MLs I have looked at).  For instance, the type of a binary
int function is displayed something like:

func(int)==>func(int)==>int

with ==> associative right to left.  The type of f(i,j)=>int is 'a
function (of i) returning [a function (of j) returning an int]'.  As I
said, takes some adjustment for most.  But occasional mental exercise
like this is probably good for the brain.
