Rosetta Code/Count examples/Full list

Full output for the Rosetta Code/Count examples#Perl_6 task. Updated periodically.

This is something of a experiment. The top 10 languages have their completed task entries marked with a circled digit in the table so you can sort on the language to see which tasks have been done. Hold down control and click on several columns to do secondary, tertiary, etc. sorts. Ideally it would be nice to be able to generate the table for any language but it is fairly intensive to generate. Once a week is ok, on demand would be unsustainable.

See Rosetta_Code/Rank_languages_by_popularity/Full_list for a full language/task completion table.

Top ten programming languages by number of task examples completed:
① Go
② Perl 6
③ Phix
④ Julia
⑤ Python
⑥ Perl
⑦ Kotlin
⑧ Racket
⑨ C
⑩ Zkl
