Detailed Description
template<typename L, typename R, typename... A>
class Pt::LambdaSlot< L, R, A >
Lambda slots cannot be compared because captured lambda values have no general equality operation. Retain and close the returned Connection to disconnect a slot, or bind it to a Connectable context.
