DEPR: Series.get_values()

[jreback]

this was never meant to be exposed to the user, is not-documented, and is just plain confusing

Hmm I think this has some pretty far reaching impacts as it's used internally below:

pandas/pandas/_libs/lib.pyx

Line 45 in 7ed1f53

f = getattr(o, 'get_values', None)

I suppose we could add some type of introspection there specific to Series but do you see this spilling over into other classes at some point as well?

[jreback]

no, want to completely remove this in favor of using _ndarray_values and .values as appropriate. too many ways of doing things. this will be easier once Sparse is an extension array.
