+`Toy_Scope` holds the variables of a specific scope within Toy - be it a script, a function, a block, etc.
+Scopes are also where the type system lives at runtime. They use identifier literals as keys, exclusively.
+
+`Toy_RefString` is a utility class that wraps traditional C strings, making them less memory intensive and
+faster to copy and move. In reality, since strings are considered immutable, multiple variables can point
+to the same string to save memory, and you can just create a new one of these vars pointing to the original
+rather than copying entirely for a speed boost. This module has it's own memory allocator system that is
+plugged into the main memory allocator.
+
+`Toy_RefFunction` acts similarly to `Toy_RefString`, but instead operates on function bytecode.
