// There is a LOT that can be done with types, but for simplicity it only does what is needed.
// The main thing is to try find the type so we don't add a duplicate (but not end of the world if 1 or 2 are duplicated as a
// trade-off to doing complex logic to resolve more complex types). The class also takes advantage that while Instrumenting we are
// always aware of our types we are adding or just explictly found.
struct Type { … };

// Represents a OpConstant*
// Will not be a OpSpecConstant* because we don't know if the value will change
struct Constant { … };

// Represents a global OpVariable found before the first function
struct Variable { … };

// In charge of tracking all Types, Constants, and Variable in the module.
// Since both Variable and Constant both rely on Types, the Types are the core thing we track
//
// Function naming guide:
//      Find*() - searches if type/constant/var is already there, will return null if not
//       Get*() - searches if type/constant/var is already there, will create one if not
//    Create*() - just makes the type/constant/var, doesn't attempt to search for a duplicate
