[issue23372] defaultdict.fromkeys should accept a callable factory

[SilentGhost]

SilentGhost added the comment:

Raymond, but Alec talks about 

  defaultdict.fromkeys(constants, factory=list)

as opposed to current solution

  d = defaultdict.fromkeys(constants)
  d.default_factory = list
  for i in d:
      d[i] = []

I wouldn't think that the dict.fromkeys should be affected by this issue.
