Damn! I suck. Outlook as a newsreader sucks. I need to use something else.

They were copied from working code. Copied *badly*? Yes. Running python via:
   Windows -> start -> run -> python 
doesn't allow cut and paste 

Here is what I tested, now cut and past from visual studio IDE 

#--------------------
def a(): print 'a'
def b(): print 'b'
c = (a,b) 
c[:]()  # typeError 
c[0]()  # expected
c[:][0]() # huh?
[i() for i in c] # too long and ...huh?
#--------------------------------------

Now, I'm extremely annoyed at my own original post, for misleading typos.

Yeah, Mikael's example is really cool! And I followed his suggestion of
making it cellphone friendly by shorting the name, like so:

#--------------------------------------
class do(list):
    def __call__(self,*args,**kwargs):
        return [f(*args,**kwargs) for f in self]
        

def a(): print 'a called'
def b(): print 'b called'
c = do()
c = [a,b]
do(c[:])() 
do(c)()    
#--------------------------------------

I prefer that last line, because [:] is very expensive to type from a cell
phone. 

In summary:
	Sorry about the hijacked thread
	Sorry about the typos
	Outlook is an odd newsreader
	Mikael's solution works
	No PEP needed for this example

Now, if I could only could do this:

	do(orchestra(conductor)).play() 

Cheers,
