There is a way to make all of this work with 2.3, and TurboGears has
tried to maintain 2.3 compatibility, so you shouldn't have to update
your Python just to use TurboGears.
As Bruno mentioned:
@expose()
def myFunction():
return "hi"
Is the equivelent of:
def myFunction():
return "Hi"
myFunction=expose(myFunction)
That's not really pretty, so TurboGears provides Python 2.3 users with
a trick that allows you to use the following syntax:
[expose()]
def some_method(self, someval):
return "Hi"
The preceding code works in both Python 2.3 and 2.4, so you can write
code that works on both versions of Python.
