Why is readding u'' a feature and not a bug?

There is a really simple litmus test for whether something is a bug: does it deviate from the specification?

In this case, the specification is the grammar, and the implementation certainly doesn't deviate from it. So it can't be a bug.

Regards, Martin

P.S. Before anybody over-interprets this criterion: there is certain "implicit behavior" assumed in Python that may not actually be documented, such as "the interpreter will not core dump", and "the source code will compile with any standard C compiler". Deviation from these implicit assumption is also a bug. However, they don't apply here.
