Both define an outer function (plus).
Both return an inner, anonymous function.
Both "close over" the variable in the parent scope.
R uses environments; Perl uses lexicals. Same logic, different syntax. 🤝

Mark StosbergI'm learning #Rust now and am surprised that my #Perl experience is perhaps more valuable than JavaScript / TypeScript experience to understand some of the concepts. Why:
- Perl has more explicit reference handling
- Perl has Moose::Roles which have some similarities in Rust traits. I haven't run into a similar pattern as much in JavaScript / TypeScript.

MarcusJust merged the go-based branch of #convos (web based irc client) to main, planning to do a stable release in a week or two. Other than a total rewrite of the backend from #perl to #go, the main interesting features are oidc SSO and proper webpush notifications working on android and ios. If you want to test the new release, the alpha images are now built using go https://github.com/convos-chat/convos/pkgs/container/convos - the svelte frontend remains more or less unchanged, will probably be upgraded to a more recent svelte and retouched for v10
sebiSo glad #perl
DateTime.pm have a $dt->truncate( to => ... ) method. Makes possible to alter a date to a "close" value, e. g. ->truncate( to => 'day' ) and a DateTime that's set to 3:54PM would be "reset" to the same day, 00::00:00AM.
