Understanding Lean's Foreign Function Interface (FFI)

WARNING

Note on FFI Interface Stability The current Foreign Function Interface (FFI) in Lean 4 was primarily designed for internal use within the Lean compiler and runtime. As such, it should be considered unstable. The interface may undergo significant changes, refinements, and extensions in future versions of Lean. Developers using the FFI should be prepared for potential breaking changes and should closely follow Lean's development and release notes for updates on the FFI system.

Big-O Time Complexities for Elixir data structures

Operation	Time Complexity
Access	`O(log n)`
Search	`O(log n)`
Insertion	`O(n)` for <= 32 elements, `O(log n)` for > 32 elements [2]
Deletion	`O(n)` for <= 32 elements, `O(log n)` for > 32 elements

	This document represents the beginning of an upgrade or migration document for GDScript 2.0 and Godot 4.0. I'm focusing on 2D
	at the moment as I'm upgrading a 2D game, but will hopefully have more to add for 3D afterward.

	## If you want more content like this, please help fund my cat's medical bills at https://ko-fi.com/kyleszklenski - thank you very much! On to the migration guide.
