Drawbacks of using boost::signal (s) ?

[Tommaso Cucinotta]

Hi all,

if I remember well, there has been a significant decrease in the
use of boost::signal variables, in trunk w.r.t. previous revisions.

Just as an example, now we have a Buffer::changed() method that
uses a WorkArea pointer (wa_) in the Buffer::pimpl object, in order
to call redrawAll() and trigger a redraw.

Isn't it better to have a signal defined in the Buffer public interface,
where interested listeners can register (e.g. GuiWorkArea) ?
