Fun Fact - Bukkit's naming vs Mojang's naming

As you may know, mojang uses different Object/Classes/Everything naming than bukkit.
While I was watching "Minecraft Documentary Part 1 HD", at (for example) 3:04 you can see part of Minecraft's code

• Mojang documents the code
• Bukkit's itemStack is named itemInstance

Here, in an older video:

• World is called level
• He uses X, Y, Z coordinates (How does this work in game, since it has X, Z, Y coords, @Bukkit team?)
• Notch uses camelCase names

One more:

• Probably some old code, like isInWater(), isInLava()

Moore:

• handleGrabTexture? Probably a function for block destroying.

Well, this was just a fun fact - and you can see that Mojang documents code better than Notch at first
