Resources on advanced variable export

Moros

So I was messing around with the engine and I was looking more in depth on how to export script variables into the inspector. The thing is I looked at the documentation and the page about this functionality is small without examples and I am struggling to make it work. I mean for basic data type export I can handle it, but now I am stuck on things like exporting an integer as a enum list. Does anyone here have a resource I can look at to help me figure out this ?

Immediate thought that occurs to me is that enums are constant not variable hence likely issues with trying to export them.

Sorry if I wasn't clear but I am not trying to export the enumeration itself , I want to export a variable with a restrained set of values defined by an enumeration. The classic way to do that in gdscript is as follow :

enum PossibleDirection {UP, RIGHT, DOWN, LEFT}
export(PossibleDirection) var player_direction

I could do that but I am trying learn advanced export using _get(), _set() and _get_property_list() as briefly described on this page of the documentation
