Some of my configuration files are online aren’t they? Raku is one of the most interesting, if not the most. I’m not an expert but it pretty much has every language construct (e.g promises) plus exotic stuff. The exotic operators are strangely intuitive (and “hyped”).

my @bin = 1..3;
@bin>>++;
say @bin;

I use it for quick CLIs with the multi dispatch CLI feature. The logo is a butterfly (or maybe it’s a raccoon).

File name, spelling, and dictionary completion exist too. This is tortured, but combining them makes a meta point? The “meta” is hard to convey, but completion doubles as a way of finding, changing, and passing keywords around. Terminals are fair game too. That’s basic completion in a nutshell (minus the magic).

Command line completion is probably another lesser known one. The command line window is minimized, but typing q: (commands) and q/ or q? (search forward/backward) opens it up completely. Wild mode configures its behaviour.

Abbreviations are another completion primitive in Vim. Since it’s full auto, it wants to be magical. <Key> presses and scripts can be replayed. Paired with custom completions and output from external tools, it transforms into advanced witchcraft and/or cursed sorcery. In my case, it just expands acronyms.
