Maarten uses it in Rugby in the creation of stubs for remote
invocation, but he would have to contrast how it might be done without
BIND as I haven't thought about it in detail.
I use bind in my FSM dialect. There, you define action blocks that are
triggered when the FSM is sent events. A single FSM can act like a
shared "engine", with BIND used to execute the actions in the proper
context--usually the one that sent the event, but could be any context
you want.
