I posted a question here about what I am upto with this.

I have $code and $args, $code is perl code in a string and $args is what I want to pass into STDIN.

From my stackoverflow post and @ikegami's help I have this so far:

//time out is from the Time::Out module.
my $ret = timeout 5 => sub {
    my $r = `perl <some_path>/ExecScript.pl '$code' "$arg" &2>1`; 
    return $r;
} ;

###########
# ExecScript.pl
######
if($ARGV[0]) {
    my $code = $ARGV[0];
    my $arg = $ARGV[1];
    open(my $fh,'|-', 'perl', '-', $arg);
    print $fh $code;
    close($fh);    
}

    Problems:
  1. I can't really pass $arg into STDIN, it just goes in as an argument
  2. I can't fetch STDERR

I looked into IPC::Run but I can't really figure how to use it? The docs don't really have method signatures and their return types, stuff like that.

Please help me out
