ChangBo Guo(gcb) 0ee91a5854 Use dict comprehensions instead of dict constructor
PEP-0274 introduced dict comprehensions to replace dict constructor
with a sequence of key-value pair, 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.
There is deep dive about PEP-0274[2] and basic tests about
performance[3].
Note: This commit doesn't handle dict constructor with kwagrs.
