 When binding to C libraries you'll often end up using `proc "c"` and also set the current context. For this you'll need to [explicity set the context](#explicit-context-definition).

 A `typeid` is a unique identifier for an Odin type. This construct is used by the `any` type to denote what the underlying data's type is.

-### 'any' Type
+### `any` Type
 An `any` type can reference any data type. Internally it contains a pointer to the underlying data and its relevant `typeid`. This is a very useful construct in order to have a runtime type safe printing procedure.
 
 **Note:** The `any` value is only valid for as long as the underlying data is still valid. Passing a literal to an `any` will allocate the literal in the current stack frame.

-#### 'Maybe(T)'
+#### `Maybe(T)`
 `Maybe(T)` is a union which *either* returns a type `T` or `nil`. In other languages this is often seen as `Option(T)`, `Result(T)`, etc. 
 
 Odin has multiple return values, so `Maybe(T)` is used less frequently or rarely in the `core` library. Instead of doing `-> Maybe(int)` you could transform it to `-> (int, bool)`.
