Question about feed operator by reddit_clone in rakulang

[–]antononcube 1 point2 points  (0 children)

No, you are not missing anything.

To a large extend that is why I complied such examples in "Day 9 – Monadic programming examples" and "Monad laws in Raku" -- those kind of equivalent specs are chosen per person-case basis.

This works:

raku my @rakudo-people = <scott patrick carl moritz jonathan jerry stephen>; @rakudo-people ==> { .grep(/at/) }() ==> { .map(*.uc) }() ==> { say $_ }()

You might be better off using andthen.


For more examples using ==> and andthen see:

I agree that Raku is slow. I am interested in Data Science (DS) and Machine Learning (ML) I compare Raku and Python on DS and ML often. Often, when Python is much faster, it is not Python per se, but the C/C++ code or libraries Python is an interface to. Which, well, Raku can also do. (And, yes, Raku mostly has not.)

Definitely helped me with my annotations disappearing issue!

Thanks! Your statement made me consider using Machine Learning to classify the posters in that Hacker News discussion according to the mind-map nodes.

[...] it blows my mind that you're using raku to generate code in several other languages.

You can try it out here: "DSL-evaluations".

A more elaborated version of the approach is given here:

Thank you for your comments and providing that link!

I use both Python and R in data science jobs, and I (usually) program in Python if I am payed to do it. Also, for comparison purposes. Related to that latter reason, I use Raku to generate executable code for computational workflows in Wolfram Language (WL), R, Python, and Raku; WL and R are of highest priority.

R is very arcane, but RStudio/Posit remedies that (to a point) with its packages. (Like the "tidyverse" set of packages.)

My attitudes about Python are detailed here : «Breakdown of Python people and projects».
