I've added template parameters to the slot class in thread_safe_signals for
specifying its signature, as slot<Signature> or slot1, etc. So now
slots can be bound to each other. I've also dropped the automatic
discovery of tracked objects, and added slot::track() functions. There is
now some syntactic sugar for bind, if a slot constructor is called with
more than one argument, then the arguments will automatically be passed
through bind(). I tried using bind<R>(), since the slot knows what its
result type should be, but gcc gave me ambiguous overload errors when
bind<R> was given a function pointer.
There is a little test program in the sandbox now too, at
boost-sandbox/libs/thread_safe_signals/test/track_test.cpp. I encountered
one problem with the bind syntactic sugar, described in the test program's
comments. I found the error message unhelpful, therefore it must be a
compiler bug :)
