Guido could have added the ternary operator 10 years ago. He didn't. Now, 
there are three possibilities:

1) he thinks that now it would be more useful than ten years ago, since
now we have listcomp, lambdas etc. Still it is not 100% convinced and he
is asking for feedback.

2) he doesn't want it, but since people has kept requisting it for ten
years, he is willing to concede it for peace of mind. He doesn't think
it would be too much harmful.

3) he really thinks most pythonistas don't want it. If the votation is
   80% against, he has a good reason to refute it forever.

I am not a mind reader, I don't know what Guido thinks. Sometimes I propend
for 1), sometimes for 2), sometimes for 3). Who knows ?

We will see.
