It would be nice to support pandas nullable dtypes:

In [7]: import pandas as pd

In [8]: df = pd.DataFrame({"a": pd.Series([1, 2, None])}, dtype="Int8")

In [9]: df
Out[9]:
      a
0     1
1     2
2  <NA>

Right now, hypothesis tries to convert the input dtype in past.column to a numpy dtype, which won't work with these new dtypes.
