Hope this helps....
Thanks! It does. I think what threw me was that while there is enough redundancy in what he states for someone more clever than me, he would have explicitly stated before hand that he was defining the operators [:=], [+'], ['if] etc.:)
But he did; specifically, on pages 405 (the previous page) to 406 of the volume, Hudak writes as follows:
For expository purposes we would like to make the state as implicit as possible, and thus we express the result as a composition of higher-order functions. To facilitate this and to make the result look as much like the original program as possible, we define the following higher-order infix operators and functions(22):
So he did in fact explicitly state beforehand that he was defining those operators. -- Benjamin L. Russell -- Benjamin L.
