Issue description

@export_enum does not support multiline
for example :

@export_enum(Item1, Item2, Item3, Item4, Item5, Item6, Item7,
                         Item8, Item9) var MyEnum = 0

an Error says : expected ")" after annotation arguments
it must be in one single line like this :

@export_enum(Item1, Item2, Item3, Item4, Item5, Item6, Item7, Item8, Item9) var MyEnum = 0

sometimes the enum contains many items and it's hard to write it all and modify it in a single line of code
