Compare this to your original:
def logFunctionCalls(function):
ec = FunctionCounter()
def decoratedFunction(*args,**kwargs):
print "Entering function:", function.__name__, ec.next()
function(*args,**kwargs)
return decoratedFunction
@logFunctionCalls
def doWork():
print "Doing Work"
doWork()
doWork()
(This is a quick-and-dirty example, but it works. A proper iterator
would do more to preserve the identity, docstring, etc. of the
underlying doWork() function. See the decorator library page on the
Python Wiki, at http://wiki.python.org/moin/PythonDecoratorLibrary.)
Also, look into the treasure trove that is itertools, especially
itertools.count.
