ChangBo Guo(gcb) d988d14801 Use dict comprehensions instead of dict constructor ... PEP-0274 introduced dict comprehensions [1], these are benefits: The dictionary constructor approach has two distinct disadvantages from the proposed syntax though. First, it isn't as legible as a dict comprehension. Second, it forces the programmer to create an in-core list object first, which could be expensive. Keystone dropped python 2.6 support in Kilo, we can leaverage this now. There is deep dive about PEP-0274[2] and basic tests about performance[3]. Note: This commit doesn't handle dict constructor with kwargs. This commit also adds a hacking rule.
