Some years ago (on the old primes when there was a 'book' section), I had posted about Maple 401, a list of advanced functionality that someone serious about writing code in Maple ought to know. But that list is not particularly current (it probably was not completely current when I created it), as I did not keep up my in-depth knowledge of more recent releases of Maple. So my question is: what is this list really missing?
Those who know me know that I don't want to hear about the latest version of the corporate message, I want to hear about core functionality of Maple that makes a real difference. Note that these are not disjoint: the Task model is clearly something missing from that list. What else?
