I was trying to reuse your #random checker for ipython but kept
running into problems. Is it working for you in numpy in actual code?

Unfortunately, when we try to unpickle the data saved with Numpy 1.0.3
in the new code using Numpy 1.1.0, it chokes because it can't import
numpy.core.ma for the masked arrays. A check of Numpy 1.1.0 shows that
this is now numpy.ma.core.

Hello,
sometime scripts and programs create a lot of data output.
For the programmer and also others not involved in the scripting but in the
evaluation of the output it would be very nice the output files could be

Hi Stephan,
I'm thinking it would nice to backport as many documentation updates to
1.1.1 as possible. It looks like the following steps should do the trick.
1) Make ptvirtan's changes for ufunc documentation.
2) Copy add_newdocs.py
3) Copy fromnumeric.py
Does that look reasonable to you?

Hi,
I've enclosed a patch for numpy.i (against the trunk). Its goal is to
add const char*
instead of char* in some functions (pytype_string and
typecode_string). The char* use raises some warnings in GCC 4.2.3 (and
it is indeed not type safe IMHO).

Otherwise, you can already
save the array and mask separately.
An other possibility is to store the MaskedArray as a record array, with one
field for the data and one field for the mask.
What about the other parameters, such as fill value?
