It's irrelevant that someone doesn't think the code is APL-inspired. Their disagreement is as much with the article as your comment. I felt like what is written in the article already implied what I then read in your comment. Credit where due, the disagreement with the article probably would've not been posted if the implications in that part hadn't been re-stated plainly. Comments like these can be useful as pointers to specific aspects of an article, where conversations can be organized under, now that I think about it.

Dunno why electroly is dragging me into this but I believe you've misread the article. When it says "His languages take significantly after APL" it means the languages themselves and not their implementations.

The article: "Let's make sense of the C code by the APL guy"

Do you think the article meant to say it was more likely that the code wasn't inspired by APL?

I think the article expresses no position. Most source code for array languages is not, in fact, inspired by APL. I encourage you to check a few random entries at [0]; Kap and April are some particularly wordy implementations, and even A+ mostly consists of code by programmers other than Whitney, with a variety of styles.

I do agree that Whitney was inspired to some extent by APL conventions (not exclusively; he was quite a Lisp fan and that's the source of his indentation style when he writes multi-line functions, e.g. in [1]). The original comment was not just a summary of this claim but more like an elaboration, and began with the much stronger statement "The way to understand Arthur Whitney's C code is to first learn APL", which I moderately disagree with.

		I unfortunately glossed over the part of the original comment that gives it substance: "The most obvious of the typographic stylings--the lack of spaces, single-character names, and functions on a single line--are how he writes APL too." That's backing for a claim. Also, I haven't once written APL. I think this might've been borderline trolling, just because of how little investment I have in the topic in reality. Sorry.
