Or yet even better:
class Job(object):
 def __init__(self, target, *args, **kwargs):
 self.target = lambda: target(*args, **kwargs)
 def __call__(self):
 return self.target()
in order to do
actions.append(Job(function, val))
actions.append(Job(function, x=val))
and then (thanks, Chris...)
results = [function() for function in actions]
or maybe (additionally or alternatively)
class ActionQueue(list):
 def addJob(self, target, *args, **kwargs):
 self.append(lambda: target(*args, **kwargs))
 def __call__(self):
 if 0: # first thought
 for job in self:
 yield job()
 else: # second thought - clean up...
 while self:
 job = self.pop(0)
 yield job()
with
actions = ActionQueue()
actions.addJob(function, val)
actions.addJob(function, x=val)
results = list(actions()) # for collecting them and having them at once
# with generator, all call results can as well be emitted as soon as 
they are available - depending what shall be done with the results
mmm... too much imagination I think... ;-)
