Why invent a new special case syntax - the ones we have work fine.
# This goes in a library
def upon(event):
def wrapper(fn):
event.set_callback(fn)
return fn
return wrapper
# Create a callback timer
alarm = Timer()
alarm.SetDuration( 100, Timer.Milliseconds )
@upon(alarm)
def callback():
print "It's time to get up, silly-head!"
Looks pretty readable to me...
