I have a longer script 'pash', that uses Term::ReadLine for history support. The only thing about 'pash' is that you hit enter twice - this allows multi-line entries.

use Term::ReadLine;

my $help = <<EOH;
pashn is a simple perl shell, it allows you to
type in raw perl, fragments and subs.

You can also run shell commands by appending
the command with a bang!

However 'my' and 'local' will only work inside
a single statement, and so multiline code can be
entered you must hit return twice.

But in return, Term::ReadLine is here to give 
us history and non-destructive backspaces, and 
multiline editing, and bash or vi keybindings, 
and of course you can easily 'use' oodles of 
CPAN modules, ?

my $terminal = Term::ReadLine->new('PASH');
$terminal->ornaments(0);
$terminal->MinLine(undef);
$| = 1;

my $prompt = "pashn; ";
while () {
        my $editbuffer = $terminal->readline( $prompt );
        while () {
                my $b = $terminal->readline('');
                last unless $b; 
                $editbuffer .= "$b\n"; 
        }

        chomp $editbuffer;
        $terminal->addhistory($editbuffer);

        if ($editbuffer =~ s/^\s*\!//) {
                print qx|$editbuffer|;
                next;
        }

        eval ("$editbuffer");
        print $@ if $@;
        print "\n";
        next;
}
