perl6 IO::Socket::INET 无法从套接字接收数据：连接被对等方重置

示例服务器：

#!/usr/bin/env perl6
my $listen = IO::Socket::INET.new(:listen, :localhost<localhost>, :localport(3333));
loop {
    my $conn = $listen.accept;
    while my $buf = $conn.recv(:bin) {
        $conn.write: $buf;
    }
    $conn.close;
}

Client:

#!/use/bin/env perl6
my $c = IO::Socket::INET.new(:host<localhost>, :port(3333));
$c.print: "{time}\n";
#say $c.recv; #commented out on purpose
sleep 1 ;
$c.close ;

服务器错误：

Could not receive data from socket: Connection reset by peer in block <unit> at server4.p6 line 5

在我尝试过的每个块的服务器中CATCH and QUIT。我应该如何捕捉这个错误？

服务器需要捕获循环块中的错误：

#!/usr/bin/env perl6
my $listen = IO::Socket::INET.new(:listen, :localhost<localhost>, :localport(3333));
loop {
    my $conn = $listen.accept;
    while my $buf = $conn.get {
        $conn.print: $buf;
    }
    $conn.close;
    CATCH { default { say .^name, ': ', .Str ,  " handled in $?LINE";}}
}

服务器的输出报告错误并保持运行以接受新连接：

perl6 --ll-exception server.p6
