Many thanks for the excellent summary, Thomas.

I concur with you, both because (even if slightly less convenient in
py2 due to needing the explicit u prefix) it's semantically consistent
with how unicode objects work, and because of it being the natural
path for py3.

I guess we could make it a configurable option, but I'm not even sure
it's worth the added complexity, so I'm mildly -1 on going down that
road, unless I can be convinced that the implementation isn't that
complicated and that there's really a *major* usability win for
certain users for whom the default is just too annoying to bear.

Cheers,

f
