Interesting that both | and ^ were supported, but | took over and ^ is still unused by the shell.

I wonder if ^ was deprecated because of the likelihood it'd be commonly used at the start of a regexp for grep, but | used to provide alternatives in a regexp was probably much less frequently used and so having to quote is was less of a problem than for ^.

Also interesting that the v3 format had both input and output filters, which is just semantic repositioning of the commands.

The ' ^ ' should be used going forward by CLI AI wrappers to mean "use the above and then | to the following"

So if you prompt, you can just "^ | table" to say "Now use the above and show me in a table." ; or just " ^ table " should suffice, ideally.

You could try

!! | some_command

Should theoretically work as youre describing in bash today!
