Declaring the size of fixed length arrays is not a new concept and is widely adopted in other languages. One principal use case for the bytearray is creating and manipulating binary data. Initializing to zero is common operation and should remain part of the core API (consider why we now have list.copy() even though copying with a slice remains possible and efficient). I and my clients have taken advantage of this feature and it reads nicely. The proposed deprecation would break our code and not actually make anything better. Another thought is that the core devs should be very reluctant to deprecate anything we don't have to while the 2 to 3 transition is still in progress. Every new deprecation of APIs that existed in Python 2.7 just adds another obstacle to converting code. Individually, the differences are trivial. Collectively, they present a good reason to never migrate code to Python 3. Raymond
