SSCCE

use v5.12;
use warnings;

STDOUT->autoflush;
STDERR->autoflush;
STDIN->autoflush;

say "Give me a cookie: ";
my $thing = readline(STDIN);
$thing =~ /^(a )?cookie$/ or warn "That was no cookie.";

say "Thanks and goodbye!";

die "exiting here";

expected output in pre/tt

Give me a cookie:                                               # waits for input
croock                                                          # manual input             
That was no cookie. at emacs_input.pl line 10, <STDIN> line 1.  # jumps to line 10
Thanks and goodbye!
exiting here at emacs_input.pl line 14, <STDIN> line 1.         # jumps to line 14

For better understanding I manually added meta info

• STDOUT in black
• STDIN in red
• STDERR resp. clickable cross-refs as hrefs
• additional comments in grey

FWIW

I've stumbled over a SO discussion which made this (half) work.

> C-u M-x compile and ... compilation buffer will be in comint mode, i.e. interactive.

(the C-u means prefix arg, a very e-lisp-ish annoyance)

I still have to find a way to make this work inside mode-compile
