Ah very good find! Thanks.

maybe this can be fixed, or at least made more consistent. I think .values is pulling out of the pandas index (so is promoted) while we do actually have an underlying int32 array.

``` python

ds.stack(b=('a',))['a'].dtype #== ds.stack(b=('a',))['a'].values.dtype dtype('int32')

ds.stack(b=('a',))['a'].values.dtype dtype('int64') ```
