APL

“APL is the language that invented first-class arrays, and is far more advanced at it than most of its successors”

“array languages can now self-host on GPUs, which, APL-pilled, I now feel is better”

“refreshingly simple and effective once you manage to overcome indoctrination you received since elementary school”

“It feels like a human communication tool more than any other PL I've mucked about with.”

“What I found was a language that rewarded deciphering APL programs and generating clever new ones.”

“In the modern world there is no place for the commercial compiler.”

“solutions in APL can be very efficient if they are written in a machine sympathetic way”

“moderately useful conceptually, weakly useful mechanically. APL is very limited in what offers you”

“neither OSS nor casually usable commercially, but instead comes under an enterprise license”

“APL allows writing some of the most readable code out there, specifically because it makes whole-application architecture imminently more visible.”

“Learning new and weird things builds brain elasticity and vocabulary for you to express new ideas.”

“has all the characters visible across the window and is interactive with a REPL”

“APL provided me with a whole different perspective on vector style operation”

“matrix multiplication, inversion, dot products seemed to be more "math oriented" than other computer languages.”

“people decided to invent APL to be even more bizarre”

“In terms of economy of notation and unified concepts, APL has no match.”

“They have friction coming from an unconventional syntax that's hard to understand without knowing the language beforehand”

“The only problem was, that line would then be almost impossible to read and understand!”

“APL warped my mind in such a way that it took almost a month to feel comfortable using anything else.”

“every generation rediscovers and gets their mind blown as an educational experience”

“I have been able to read my own code and refactor stuff I've written months ago fine”

“Completely different than APL, which has had perl's write-only label applied to it by programmers not used to reading terse mathematical notation.”

“usually considered "write only", as in impossible to read what someone else wrote.”

“Array languages are a surprisingly natural fit for audio synthesis beyond just novelty.”

“APL originally had a lot of its own symbols with very little reuse, and clear rules”

“Learn the true power of array-like thinking and strong use of symbols.”

“the terseness of APL helps a great deal because the required context is never far away”

“the original APL has defects, due mainly to the fact that it was an incomplete programming language”

“Whitney's projections and views solve a tremendous amount of the problems that macros solve”

“if it wasn't pay to use, or just, an absolute pain to install”

“There's a lot to love in the APLs even you ultimately don't buy the fanboy arguments”

“Dyalog enables BIG to react quickly to changing needs and provide custom solutions tailored to individual clients.”

“Dyalog was selected as the replacement system to provide the tools and expertise in-house”

“So the notation isn't just about readability, it's a tool for thinking about the operations.”

“they seem to be perfect for those who have developed an intense hatred of boilerplate and explicit loops”

“Perl and APL are just way too dense compared to Go and Python”

“capable of producing some of the most readable and maintainable codebases out there”

“after learning APL to a high level, it now reads like a simple, direct expression of intent”

“extreme density means you can see 'more' of the program on a given page”

“tic-tac-toe in a single short line of code is cool—doesn't mean many people get over the syntax”
