But that behavior is specific to Jupyter and so it could similarly
provide auto-complete or syntax highlighting for usage of
`smf.ols(formula=...)`. Like PyCharm provides syntax highlighting for
strings used as the `pattern` argument for the various functions of the
`re` module. So if it's only for the sake of auto-complete or syntax
highlighting, this is on the IDE and not on the language, in my opinion.

I get auto-complete on column names in Pandas when I'm in Jupyter. But
yes, I agree with you.

I don't see what's wrong with the status quo:
smf.ols(formula='Lottery ~ Literacy + Wealth + Region', data=df)
If I understand correctly you want to use instead:
smf.ols(formula=df.Lottery ~ df.Literacy + df.Wealth + df.Region)
Or since some people favor indexing over attribute access for
column names:
smf.ols(formula=df['Lottery'] ~ df['Literacy'] + df['Wealth'] +
df['Region'])
Both alternatives are much more verbose since you have to repeat the
`df` part or even worse the brackets for indexing. In any case you
need
to type the column names that you would like to include and there's no
auto-complete on column names that would help you typing it. So I
don't
see what's the benefit of the operator version.
In addition this requires Pandas to implement the modeling but there's
much more to Pandas than just modeling so perhaps that better
remains a
separate project.
