rename Axis.translate to Axis.index

or maybe keep both and have .index for single label and .translate for single labels + all other stuff (slices, groups, whatever).

or to_index?

We already have LArray.indexofmin/max and AxisCollection.index, I would rather keep with the standard .index and not introduce one more term.

translate is only for internal use, right?
In any case translate doesn't speak for itself.
IMO, it's OK if Axis.index returns more than one index in some cases.

It was indeed meant this way. But I just came on a problem where I had to use it for a user who wanted to know the position of a particular label on a sorted array. Ie what is the rank of 'belgium' in an array sorted by country, and the only way I came up with was:

sorted = array.sort_values('geo')
rank = sorted.geo.translate('belgium')

Truth be told, I realize now that it is really a workaround for the fact we do not have a rank method yet. See #158.

OK. So Axis.index?

[gdementen]

I think that would be better in any case.
