 In general, we're not exhaustively strict about coding style, but there are some preferable guidelines to follow that have been adopted from what we know about the original codebase:
 
 - Indent: 2 spaces
-- `PascalCase` for classes and function names.
+- `PascalCase` for classes, function names, and enumerations.
 - `m_camelCase` for member variables.
 - `g_camelCase` for global variables.
 - `p_camelCase` for function parameters.
