I thought Heroku only suppoted Ruby and node.js. Can someone explain what is going on here? Does it run arbitary executables, but it handles Ruby in some more powerful way?

For who? I don't think anybody who actually writes code is going to be confused by += No need to race to the bottom any faster guys.
Haters need to take a hard look in the mirror. I made a bland statement of common knowledge about readability. Never mentioned confusion. Edit: pussies.
I feel like the title of this post would make someone over the age of fifty's head explode.

INSTALLED_APPS = INSTALLED_APPS + (...) can be rewritten as: INSTALLED_APPS += (...) No?
Yep. It could be argued that the first is more readable though.
x += 2
x = x + 2
1) The first statement basically says: Add 2 to x, while the second says: Take x, add 2 and add that to x.. Which is one more step.
2) When a variable is repeated multiple time, I always read the line multiple time to make sure there is no error. For instance, in english "On the screen, there there is a xyz". I'll stop and read that sentence a couple of time to try to understand it.. and then realize it's an error. Likewise, when I see x = x + 2, I think "Is it a mistake?" I.e. did the author wanted to write: y = x + 2.. if not, why does he repeat himself?

I disagree: your statement does not in fact reflect conventions on common readability. If anything, a programmer should be able to read s = s + (...) just as well as s += (...). They both seem obvious to me but as a Python programmer, I prefer the latter.
However, one of python's main design goals is readability. That's why it does not have the i++ operator in preference to i = i + 1, for example. No switch keyword either. +=, etc managed to squeeze in though.
More specifically, one of the forms has a thousand years+ of algebra notation behind it, the other does not. I made no statement over whether pro programmers would find it confusing, but on the readability count, analogues to mathematics win.

Personally, I find: x += 2 Easier to read then: x = x + 2 For many reasons.. but mainly: 1) The first statement basically says: Add 2 to x, while the second says: Take x, add 2 and add that to x.. Which is one more step. 2) When a variable is repeated multiple time, I always read the line multiple time to make sure there is no error.
