Here's another confusion to add to the pile (from irc, just now):

18:20:25 <siak> I tried short version of while loop but it didn't work
18:21:12 <siak>  until ollama pull llama3.3; { echo 'oh!';  sleep 3; }
18:22:52 <Mikachu> you need { } around the condition and remove the semicolon
18:22:57 <Mikachu> and then it will also work without shortloops set
18:23:19 <Mikachu> because the condition for a while/until loop can be
a list, it's not clear where you want the condition to end and the
loop body to begin otherwise
18:24:07 <Mikachu> if you reread the "alternate forms for complex
commands" section, you'll notice short_loops only affects commands
with
"sublist", not ones with only "list"
18:24:42 <Mikachu> and that both while and until explicitly say "note
the limitations on the form of list mentioned above."
18:24:48 <llua> the plague~
