@TomNicholas Probably I was bit confused by the current docstring. I think I understand now and there should be no problem at all.

According to the current docstring it should already work that way for `argmin`/'argmax`:

**Reduce this DataArray’s data by applying argmin along some dimension(s).**

**Returns: New DataArray/Dataset object with `argmin` applied to it's data and the indicated dimension(s) removed**

But this behaviour is broken currently (works only for one given dim).

My main concern for changing the API as suggested above is, how should we discern (at least for `argmin`/`argmax`), if the user want's to:

1. reduce **over all** given dimensions? (current behaviour according to docstring)
2. reduce **along all** given dimensions? (suggested behaviour by @johnomotani [please correct if I'm wrong])","{""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,594594646
