Re: [Pytables-users] ANN: PyTables 3.0 final

Yes, congratulations on the new release folks! I am trying out some of my codebase with 3.0.0 at present.

- All read methods now have an optional *out* argument that allows to
  pass a pre-allocated array to store data.

I have a question about the above. And that is whether this is available when reading slices?

Looking thru the master branch codebase, it seems that a bit of user code like:

hotspot = h5f.root.anom[firstindex]

where I am taking a 2D plane out of a 3D array using just the first index, will use __getitem__() which in turn uses _read_slice(startl, stopl, stepl, shape). So at present, the 'out' parm is not available for slicing?
