Bit of pedantry but I don't think traditional unix shell (like this) follows repl model; the shell is not usually doing printing of the result of evaluation. Instead the printing happens more as a side effect of the commands.
I remember my first shell programming I ever did was batch in windows back in the 3.11/95 days.
The first line was always to turn off echo, and I've always wondered why that was a decision for batch script. Or I'm misremembering. 30 years of separation makes it hard to remember the details.
Echo in that case prints command lines before executing them. Its analog is `set -x` rather than `echo`.
It’s a shell, not the whole thing. The whole thing is the shell+kernel+programs.
Even if you view the system as a whole the printing is deeply intertwined with the evaluation, which is very different from repl where eval returns a value and print prints it
It prints a prompt.
That's not what print in repl means.
