[asio-users] Stream's lowest_layer() public member function

[Alterman, E. <Eugene.Alterman@Staples.com>]

Exposing a lower layer via a public method is IMHO a flaw in the design that
violates layering. My guess is that it is only used for connection
establishment (connect/accept). After a connection has been established a
lower layer is not supposed to be accessed directly, and providing
unrestricted access to it is potentially unsafe.
