I'm not sure why that's surprising. Raku started out as Perl 6. Perl was designed primarily for use in a shell environment. Convenience features like the arguments to MAIN bit are in line with Perl philosophy.
Agreed. I didn't know about these features - I've never written any Perl before - and I do find them kinda interesting and cool. But not really surprising.
A less clickbaity title might be "Exploring Raku's built-in shortcuts for CLIs" or something. Still 6 words. And I still would have clicked and enjoyed the article! Really appreciated its positive tone and clear examples!
Oh, I've got no complaints about the article or even its title. Few people learn Perl or Raku these days so it would be surprising for most people.
I thought it was interesting myself - Perl's my go-to scripting language but I never used Raku. I might consider it next time I have a non-trivial scripting project.
As someone who picked up Raku without knowing anything about Perl (besides the fact that it had something to do with regex), it was a little surprising :)
What makes Perl or Raku interesting? What are some applications where they are the ideal languages?
