ChangBo Guo(gcb) 69fef14509 Performance: leverage dict comprehension in PEP-0274 ... PEP-0274 introduced dict comprehensions to replace dict constructor with a sequence of length-2 sequences, these are benefits copied from [1]: 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. Nova dropped python 2.6 support, we can leverage 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 kwagrs. This commit also adds a hacking rule.
