[Feature] Integrate with LSP to be able to iterate over enums

[rkmiec]

I am aware that it would be a huge change, but being able to increment/decrement over enum values back and forth would be an awesome extension. For one of the projects I'm working on I have exported few enum sets to my config and already missed it when trying to increase not exported one.

This would be a really cool feature to have!
