Can't build asyncnet example on macosx

[Angluca]

    import asyncnet, asyncdispatch
    
    var sock = newAsyncSocket()
    proc onConnect(future: Future[void]) =
      echo("Connected in future!")
      for i in 0 .. 50:
        var recvF = recv(sock, 10)
        recvF.callback =
          proc (future: Future[string]) =
            echo("Read ", future.read.len, ": ", future.read.repr)
    
    var ft = connect(sock, "127.0.0.1", Port(12345))
    ft.callback = onConnect
    
    runForever()
    
    
    
    error:
    client.nim(13, 3) Error: type mismatch: got (Future[system.void], proc 
(future: Future[system.void]){.locks: <unknown>.})
    but expected one of:
    proc callback=(future: FutureBase; cb: proc ())
    proc callback=[T](future: Future[T];
                     cb: proc (future: Future[T]))
    
    

Must remove connect or recv line can build it. (v0.14.2).

it's (future: Future[void]) bug.
