Thoughts on the depth of enums from the settings API

[Gobot1234]

I think these kind of lengths of enums are fine, they are just pushing it

viscous = Viscous(solver=solver)
viscous.model = viscous.model.K_EPSILON
viscous.k_epsilon_model = viscous.k_epsilon_model.REALIZABLE

But some seem to really be incredibly deeply nested and it's especially problematic because you have to double the number of characters to actually assign anything to it. This is an example of the first thing I pulled out of the settings API

display_states_child = ...display_states.create(...)
display_states_child.boundary_marker = display_states_child.boundary_marker.DONT_SAVE

or a less contrived example

echem.electrolysis.options.bc_type = echem.electrolysis.options.bc_type.TOTAL_VOLTAGE

Whereas if you just use a string you get rid of half the characters. I feel like this isn't practical to use even with autocomplete cause you've got to go back and read this 85 character string (it's almost so large it would be broken onto 2 lines).

Do people have any thoughts/ideas on how this could be improved? In my mind using str here is better and it can be type checked with typing.Literal but that's not ideal for pyconsole.
