If i post here, this is because i want to make a sub which execute some file (or a perl sub), and returns a 4 elements list : the child pid, the in, out and stderr filehandles the function generates

That describes IPC::Open3's open3 almost exactly. Here's a simple wrapper that provides the desired interface: 

use IPC::Open3 qw( open3 );

sub create_child {
    my $pid = open3(
       local *TO_CHLD,
       local *FR_CHLD,
       local *FR_CHLD_ERR,
       @_
    );
    return ( $pid, *TO_CHLD, *FR_CHLD, *FR_CHLD_ERR );
}
