getters and setters

[Ofnuts]

what should i do in place of that dictionary of constant keys and/or the function that returns it?

i am thinking of making it be a global to the module and have the get_opts() function return (maybe a copy) of it and also have the set_opts() function use the keys from it in place of option_names_all in the inner loop scanning the passed option, so there just a single place defining what are the options to set and what are the options to get.  it would still by a dictionary with constant keys.

what is a named tuple reflex?

It's using a named tuple where it makes sense.
