<() equivalent

[veilm]

from skimming gemini's suggestions it looks like regular shells have a feature cmd arg1 arg2 <(cmd2 foo) which makes arg3 a temp file equal to the output of cmd2 foo?
idk if that's it, but either way seems potentially useful. but special syntax is too much for this, jts add like a tmpf binary that will take stdin, write to a temp file, and output the temp filename

then you just have cmd arg1 arg2 [cmd2 foo | tmpf]
done it's clean
