How does one select / slice a dataarray with no index? Does isel work but not sel?

isel will definitely work unchanged.

For .sel, there are two choices: - Raise a TypeError about how an index is required (this would be the strictest option) - Just pass on the key arguments for dimension without an index unchanged on to .isel (this is the approach I currently prefer, because it's a bit more convenient and also preserves backwards compatibility)
