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,
