There was a problem hiding this comment.
This is needless info: by not being exposed outside of pd.core makes this an internal function. No need to be explicit.

factorize_from_iterabledidn't return anCategoricalIndex, if its input was a categorical-like. Instead it returned a plainCategorical. This PR fixes that + adds return types.Also makes the return value for
factorize_from_iterablesclearer and easier to read.
