Since we're discussing the issue, I've added an experimental disconnect() member function to signals that allows one to disconnect equivalent slots, e.g.,

void foo(); void bar();

signal<void()> sig;

sig.connect(&foo); sig.connect(&bar);

sig.disconnect(&foo); // disconnects foo, but not bar

Glad to see it.

We could also reconsider the += and -= syntax, since support for -= now makes some sense.

.NET delegates, which are equivalent to boost signals in .NET-land, uses the += and -= operates to add and remove event handlers. But I am sure you know that already <g> .
