String-only key dicts are special in CPython and I think they merit their own micro benchmark.

Data structure read access:
  23.6 ns       read_list
  23.4 ns       read_deque
  26.2 ns       read_dict
  23.2 ns       read_strdict

Data structure write access:
  25.6 ns       write_list
  27.1 ns       write_deque
  33.7 ns       write_dict
  29.1 ns       write_strdict

(I hope this is not worth creating a ticket…)

@rhettinger, please review.
And thanks for the script! It's a really nice way to compare and tune these basic operations.
