For people who are curious as to why people moved to Python. Some will say because college kids are taught Python, but I think that is a side effect.
Perl is an old language, pre OOP. It's a language from the 90s, when everyone was hacking together code not knowing what the future would be like. There is a lack of organization. Perl is like C in syntax, features, and in speed. Python is like C++. Every failing you can find in Perl stems from it being a PP language first, from dirty code to kids not learning it in college.
Raku attempts to address every failing of Perl, yet be better than Python. If it succeeds, who knows, but I hope it gets at least a chance to make something of itself.
