GitHub - jeffomatic/jl_signal: A reasonably fast and tidy ... A signal is an object that can invoke an arbitrary list of connected functions. These functions are commonly referred to as slots, although the jl_signal API does not use the term explicitly. Slot functions are connected to a signal, and when you emit the signal, each connected slot function will be called.
