i encountered this problem when i'm writing a program for packaging
files.
the program generates tasks according to description file.
and tasks are deferent from each other, and should be excuted at the
last of program.

i have experience on Lua and have learned about scheme and haskell, so
i wrote the wrong code in python.

now my solution is, using class taskCreator to create tasks and put
them into tasklist.
class taskCreator:
    def __init__(self, proc, input, output):
        self.proc = proc
        self.input = input
        self.output = output
    def call(self):
        return self.proc.call(self.input, self.output)
'proc' is generated by procCreators, it's specified.

it looks more complex than lambda one.

is there any other simple way to implement it?
and does the taskCreator mean 'create a new scope'?

Suggestions will be appreciated. Thanks.

PS: i'm a newbie in Python (started from today)
