IIRC, one of your proposals for Python 3.0 was that single-line blocks would be banned. Is my memory wrong?
It's a proposal. I'm on the fence about it.
A difficult decision indeed. Most single line blocks I've seen would be more legible if they were written with two lines each, so I'm carefully avoiding them as a personal rule. But each rule has exceptions. There are a few rare cases, usually sequences of repetitive code, where single line blocks well succeed in stressing both the repetitive structure and the differences, making the code more legible then. As someone well put it already, this is all about Python helping good coders at writing good code, against Python preventing bad coders from writing bad code. Sadly enough, looking around, it seems Python could be a bit more aggressive against bad practices in this particular case, even if this might hurt good coders once in a while.
