50- Naming: `snake_case` for functions/variables, `PascalCase` for types (matching Rust conventions)

52▶### Error Handling
53- Non-null assertions (`!` in TS) -> `.unwrap()` or similar panic
54- `CompilerError.invariant()`, `CompilerError.throwTodo()`, `throw` -> `Result<_, CompilerDiagnostic>` with `Err(...)`

54▶- `CompilerError.invariant()`, `CompilerError.throwTodo()`, `throw` -> `Result<_, CompilerDiagnostic>` with `Err(...)`
55- `pushDiagnostic()` with invariant errors -> `return Err(...)`
56- `env.recordError()` or non-invariant `pushDiagnostic()` -> accumulate on `Environment` (keep as-is)
