Call me strange, but I regard this as a good place to use a functional style
- IE, to use reduce, and furthermore I regard this as a good example of why
reduce is useful for more than just summing numbers:

Hi,
I am looking for a fast internal vector representation so that
(a1,b2,c1)+(a2,b2,c2)=(a1+a2,b1+b2,c1+c2).
So I have a list
l = ['a'a,'bb','ca','de'...]
I want to count all items that start with an 'a', 'b', and 'c'.
What I can do is:
count_a = sum(int(x[1]=='a') for x in l)
