TCPConnectionFunction is a delegate and not a function pointer

[WebFreak001]

/// Callback invoked for incoming TCP connections.
@safe nothrow alias TCPConnectionDelegate = void delegate(TCPConnection stream);
/// ditto
@safe nothrow alias TCPConnectionFunction = void delegate(TCPConnection stream);

This makes the listenTCP_s documentation stating that it accepts a function pointer wrong.

Is this intended? Would changing this break old code?

Calling toDelegate with a delegate is a no-op. This seems like a mistake made when copy-pasting.
