Hara, I am reading the discussions in Pull 1465, and I have to say I use this
kind of code all the time:

aa[x]++;

It's very handy. It's similar to a Python defaultdict:

>>> from collections import defaultdict
>>> d = defaultdict(int)
>>> x = 'c'
>>> d[x] += 1
>>> d
defaultdict(<type 'int'>, {'a': 1})


If you disallow that If you disallow that, I will have tons of broken code. And
I have to replace:

aa[x]++;

With:

if (x in aa)
    aa[x]++;
else
    a[x] = 0;

This makes D code longer, and it doesn't make it safer.
