In TXR, we can easily recall the entire function definition at the REPL, and resubmit it, without requiring any external IDE.

Furthermore, if you have the kind of workflow where you have individual REPL commands produce results that are used by subsequent commands, the TXR Lisp listener has good support for that. When you recall an input line from history, you can use Ctrl-X Enter to execute it rather than just Enter. When you use Ctrl-X Enter, it will keep the history position and move to the next line in history rather than return to the current context. So using Ctrl-X Enter multiple times, you can resubmit a sequence of historic lines in order.

that's pretty nice!

you might want to switch to the standard gnu readline keybinding for 'submit the current input line for execution and recall the next line in history', which is control-o. aside from the synergistic effect of being able to use the same keybinding in txr, bash, python, etc., it's a command which you frequently want to use several times in a row, and binding such a command to a sequence of two keystrokes makes it disproportionately more clumsy. you may have noticed recent versions of emacs permit you to run a keyboard macro repeatedly with c-x e e e, and it's a huge usability improvement

I see in the readline sources that it was added in 2021. (The git history of Chet Ramey's repositories is horrible; he just adds big patch bombs with no individual commits.)

I independently conceived the feature in 2015. I had not seen it anywhere before that, nor have I seen it since!

    linenoise: submit and stay in history.

I see the readline source code gives credit to copying this feature from the Korn shell. In misc.c there is a comment:

  /* The equivalent of the Korn shell C-o operate-and-get-next-history-line
     editing command. */

(Where would Bash imagination be without Korn.)

I see in the ksh93 sources that this appeared in or before 2012. (Again, patch bomb wall.)

i've definitely been using this feature in bash since before 02021, probably before 02012
