Fake Data Structures

[shakna-israel]

One of the dev teams is requesting a "fake" data structure section (looks like C, but is actually just Lua, so not the same memory system). Not sure if it's entirely in scope for functional... But we'll see what we can do.

Requests:

• Enum
• Struct
• Union (and/or variant from C++17)
• Pair
• Typed tables (i.e. vector from C++)
