Now I used Xamarin's Find-Usage-Feature, found one usage in ae and realized that there is no reason for using the keyword `new`, as Data is a struct (and so one does not need `new` unlike in C#) ...

You want to use it INTERNALLY as bytes, but the external interface can accept almost anything. Thank you very much! Now it makes sense and I understand.

About void[] and asockets
For sure, some might know ae. I am trying to use it as TcpServer. I got almost everything working fine concerning connection establishment and disconnecting. But there is one thing that makes it hard for me to understand, how to handle data. https://github.com/CyberShadow/ae/blob/master/net/asockets.d Well, what are these void-arrays for real? I mean, they contain data what does not make them really void, does it? And how to I get received data out of Data.content[]? How to use TcpConnection.send()? E.g. for sending a string?
