Inspired by some Conor Hoekstra YouTube videos, I tried doing some baby steps in APL and also convert my small lines to point-free style. But for this (percentage of rolls of 4, 5, or 6 in 1000 die...

I have been learning the Factor and J languages to experiment with point-free programming. The basic mechanics of the languages seem clear, but getting a feeling for how to approach algorithm desig...

I've found in 'addons/math/misc/brent.ijs' implementation of Brent's method as an adverb. I would like to build a Newton's method as an adverb too but it's much harder than building tacit verbs. ...

As a beginner in J I am often confronted with tacit programs which seem quite byzantine compared to the more familiar explicit form. Now just because I find interpretation hard does not mean that...

I'm a newcomer to J and I've been trying to create a Fibonacci function as an exercise (always the second function I create when learning a language). I just can't figure out what exactly is wrong ...

I have seen a lot of functions being defined according to the pattern (f .) . g. For example: countWhere = (length .) . filter duplicate = (concat .) . replicate concatMap = (concat .) . map Wha...

I've been using J for a few months now, and I find that reading unfamiliar code (e.g. that I didn't write myself) is one of the most challenging aspects of the language, particularly when it's in t...

Say I have a mean function defined like so: mean xs = sum xs / (fromIntegral $ length xs) but I want it in some tacit form, like this: mean = sum / (fromIntegral . length) Is there a built-in...

Is it possible to use/implement tacit programming (also known as point-free programming) in Lisp? And in case the answer is yes, has it been done?

I know all 3 are related, and I've seen quite a few answers for problems in Project Euler written in J, and a few written K. What I'm wondering is, which would you suggest learning, and where...

I'm currently learning the fascinating J programming language, but one thing I have not been able to figure out is how to filter a list. Suppose I have the arbitrary list 3 2 2 7 7 2 9 and I want ...

What exact role do higher-order combinators (or function producers) hold in concatenative and tacit programming? Is there another way to implement a concatenative programming language rather than ...

Has an emulation of J style of super condensed tacit programming via verbs, adverbs, forks, etc., ever been attempted via libraries for mainstream functional languages? If so, how successful was t...

It's not a practically important issue, but I'd like to see an example of tacit programming in F# where my point-free functions can have multiple arguments (not in form of a list or tuple). And se...
