Since state is a reserved keyword in Truffle's guard mechanism, it should not be possible to use it in a guard definition as this can cause serious problems. The annotation processor should either reject the state keyword in guard definitions or the state temporary variable produced by the processor should be renamed to avoid this conflict.

make_future_dataframe doesn't support regressors currently. So code like:

m = Prophet()
forecasts = m.predict(m.make_future_dataframe(periods=7))

gives an error like:

ValueError: Regressor 'var' missing from dataframe when attempting to generate forecasts

I'm happy to announce that I'll be writing the second edition of Data Science at the Command Line (O'Reilly, 2014). This issue explains why I think a second edition is needed, lists what changes I plan to make, and presents a tentative outline. Finally, I have a few words about the process and giving feedback.
