A small quibble: I'd like to see a benchmark of a 'u' function implemented in C. Even if it was quite fast, I don't think such a function would bring the same benefits as restoring support for u'' literals. You claim that, but your argument doesn't actually support that claim (or I fail to see the argument).

Python 2.6 code: this = u'that'

Python 3.3 code: this = u('that') Not source compatible, not elegant. (Even though 2to3 could make this fix, it's still kinda ugly.) Eh? The 2.6 version would also be u('that'). That's the whole point of the idiom. You'll need a better counter argument than that.

So the idea is to convert the existing 2.6 code to use parenthesis as well? (I obviously haven't read the PEP -- my apologies.)

Then I primarily object on ergonomic reasons, but I still think it's kinda ugly. ;)
