Hello Andrew;
(I thought I might have sent some bait. Sorry about that.)
As one of those APL programmers who, in the days before all thes new things,
problems needed to be solved, and there were plenty of them. I never felt
the need to play such games as APL "golf." (or a glorified "Name that Tune"
if you will) They just turned into debates about the definition of "token".
Part of my appreciation of cut: that it crystallized methods I had in my own
toolbox. The old tool was abandoned posthaste.
The benefit of an excersise would be the same as benefit of any other
excercise (and I am not going to explain this last statement any further).
Well, this grasshopper doesn't see it. hiho.

Hello, randy.
I'm not clear on the benefits of such an exercise. I don't know whether I
would term the attitude reflected as primitivistic, or simply Luddite.
I think this kind of language was completely uncalled for. Nowhere in my
posting I suggested to abandon cut and key in favor of grade and iota.
The benefit of an excersise would be the same as benefit of any other
excercise (and I am not going to explain this last statement any further).
Also, if you take time to read posting carefully you will see that those
are
not even called excersises, but illustrations. And they illustrate simple
idea: for decades apl users used grade and iota to get some (maybe even
most)of the functionality of key and cut until APL2 itroduced enclosed
arrays.
I recall the problems I worked on which the appearance of these concepts
seemed to cover quite well, so much so that I no longer saw the need to
I am not privileged to share memories with you, Randy, so I do not
understand this reference. If it was intended as an argument, please
elaborate.
recall SKAB(stone knives and bearskins) solutions.
