#2004: NA incompatible with astype method.

     Type:  defect      |      Status:  new        
 Priority:  normal      |   Milestone:  Unscheduled
Component:  numpy.core  |     Version:  devel      
 Keywords:              |

 To wit:

 {{{
 In [13]: x = ones(5, maskna=1)

 In [14]: x[2] = NA

 In [15]: x.astype(double)
 ---------------------------------------------------------------------------
 ValueError                                Traceback (most recent call
 last)
 /home/charris/<ipython-input-15-c95438174230> in <module>()
 ----> 1 x.astype(double)

 ValueError: Cannot assign NA to an array which does not support NAs

 }}}

 I suspect the easiest thing to do here is propagate the MASKNA flag.
