Why data in DataFrame(data) can be a generator but not an iterator?

[holymonson]

Generator inherits from Iterator, Iterator inherits from Iterable. And list([iterable]) takes an Iterable as argument.

So, why data in DataFrame(data) can't be an Iterable?

pandas/pandas/core/frame.py

Lines 381 to 383 in 620abc4

	elif isinstance(data, (list, types.GeneratorType)):
	if isinstance(data, types.GeneratorType):
	data = list(data)

pandas/pandas/core/frame.py

Lines 407 to 408 in 620abc4

	elif isinstance(data, collections.Iterator):
	raise TypeError("data argument can't be an iterator")

I think we'd be open to making this work (by consuming the Iterable into a list).
