Re: Emacs like line editing during perl input.

in gnu.emacs.help i read:

it'd be a lot better answered in comp.lang.perl.misc or .modules.

that's all that is provided by your system's terminal driver.  (probably
there are some other functions too, but nowhere near what emacs provides.)
most likely you want to special case terminal input to use Term::ReadLine.

| NAME
|        Term::ReadLine - Perl interface to various "readline"
|        packages. If no real package is found, substitutes stubs
|        instead of basic functions.
| 
| SYNOPSIS
|          use Term::ReadLine;
|          $term = new Term::ReadLine 'Simple Perl calc';
|          $prompt = "Enter your arithmetic expression: ";
|          $OUT = $term->OUT || STDOUT;
|          while ( defined ($_ = $term->readline($prompt)) ) {
|            $res = eval($_), "\n";
|            warn $@ if $@;
|            print $OUT $res, "\n" unless $@;
|            $term->addhistory($_) if /\S/;
|          }
