It's easy to write in pure Python:

def all(iterable):
     for item in iterable:
         if not item: return False
     return True

And its cousin, any:

def any(iterable):
     for item in iterable:
         if item: return True
     return False

Pros: See the "What's new" document  
http://www.python.org/doc/2.5/whatsnew/whatsnew25.html

Cons: As always with any "dot" release, extension modules are incompatible  
and have to be recompiled. Even a year after the 2.5 release, you may have  
some problems finding precompiled binaries. Ensure that all your required  
libraries are available for 2.5
