Description (last modified by andrew.mathas)

Instances of the GlobalOptions class in sage.structure.global_options do not pickle, which is annoying and causes various problems. (This is a defect.)

In addition, when the GlobalOptions class was introduced it was suggested in sage-dev that it "would be nice" if we could implement the syntax used in the IPython configuration:

    A.options.foobar = 1

in addition to


Implementing this is an enhancement, which is why this ticket is listed as an enhancement!

This (soon to be uploaded) patch will implement both of these features.

As I am cleaning this up a related question comes to mind: the name GlobalOptions is slightly unfortunate because instances of this class are really just options for an associated family of objects. I can sort of forgive myself for using this name for the class, but in all of the instances of this class the associated "parent" classes have a global_options method that points back to its options class. This method is now being enshrined more firmly inside the code because it is exploited to allow pickling. I would be happier if these methods were simply called options, rather than global_options, even though this change would necessitate deprecating the existing global_options methods.
