However..
Why do all that when you can just
str = "Hello World"
print str * 2
(Maybe I missed some concept that this small example doesn't accuratly reflect)

Hi everyone,
So let's try to squash this one now. There are more interesting problems
to solve. Or other flame wars to fight.
Let me see if we can do something constructive. I've been doing a
shallow, superficial study of the Ruby language at the moment. One of the
things I've been impressed about is that they've managed to make lambdas
look non-threatening to people with their syntactic sugar of "code
blocks".
For example,
## Ruby #####################
def twice
yield
yield
twice { puts "hello world" }
#############################
This prints out "hello world" twice in a row: the twice() function takes
in an implicit "code block", which it can later call by using their
'yield' statement. What the Ruby folks are doing is trying to make the
use of higher-order procedures look really simple. In fact, most of the
encouraged idiom style I've seen so far extensively uses this code style
pervasively (especially for iteration), and that's very admirable.
The exact functionality can be done in Python, but it does look a little
more intimidating at first:
## Python
def twice(f):
f()
f()
twice(lambda: sys.stdout.write ("hello world\n"))
This does the same thing, but it looks a little scarier because the
concepts needed to grasp his are superficially harder than that in the
Ruby code.
Anyway, let's derail off this regex flamewar and get us back to talking
about code and about stuff that actually matters, like learning how to use
functions well.. *wink*
