Hi Todd, I'm a computational biologist and my knowledge is limited to what I need to do data science and data analysis in my field.
So far, after a few years, I developed a very shy ability in programming languages. Luckily, having Perl 5 as my first love. Perhaps, at the time I was able to use Moose to support OO. Then I had to do a job with Python and I didn't know the language itself at the time. Perhaps, nowadays I have skills enough to Perl/Python/R also C/C++, but I still missing skills in Raku, perhaps by the time or perhaps because I have some language addiction. But, as far I follow this group, trying to learn something, I saw you doing some questions. And somehow I notice you have more knowledge than me in this long waited new-born (after 15y) language. That's why, as a community-developed language (including docs) I'd like to suggest to you help to improve the docs. This way, when I have - with some lucky - free time, I may learn with you and all others that wrote these docs.
