# Files to Standardize Namespace Usage

## Pattern 1: Files with Explicit Namespace Blocks
- src/type_inference.hpp
- src/llvm_type_converter.hpp
- src/error.hpp
- src/error_type.hpp
- src/type_system/advanced/**/*.{cpp,hpp}
- src/error_handling/advanced/**/*.{cpp,hpp}
- src/runtime/**/*.{cpp,hpp}

## Pattern 2: Files Using "using namespace" Directives
- src/type_system/advanced/type_checker.cpp (using namespace core)
- src/runtime/web_impl.cpp (using namespace pryst::runtime::web)
- src/generated/*.cpp (using namespace pryst, antlr4, antlrcpp)

## Pattern 3: Files with Nested Namespaces
- src/error.hpp (pryst::types)
- src/error_type.hpp (pryst::types)
- src/type_registry.hpp (pryst::types)
- src/runtime/web*.{cpp,hpp} (pryst::runtime::web)
- src/type_system/advanced/**/*.{cpp,hpp} (pryst::core)

## Standardization Rules to Apply:
1. Use explicit namespace blocks with proper indentation
2. Remove "using namespace" directives
3. Use consistent nested namespace style:
   ```cpp
   namespace pryst {
   namespace types {
   // code
   } // namespace types
   } // namespace pryst
   ```
4. Remove redundant pryst:: qualifiers inside pryst namespace
5. Keep sub-namespace qualifiers (types::, core::, runtime::) when referencing across sub-namespaces

## Priority Order:
1. Core type system files (type_registry.hpp, types.hpp)
2. Error handling system (error.hpp, error_type.hpp)
3. Runtime implementation files
4. Generated files (minimal changes needed)

## Progress Tracking:
[x] Core Type System
    - [x] type_checker.cpp (fixed duplicate methods, namespace consistency)
    - [ ] type_registry.hpp
    - [ ] types.hpp
[ ] Error Handling
    - [ ] error.hpp
    - [ ] error_type.hpp
[ ] Runtime Implementation
    - [ ] web_impl.cpp
    - [ ] io_impl.cpp
[ ] Generated Files
    - [ ] parser files
    - [ ] lexer files

## Known Issues:
1. Duplicate method definitions found and fixed in type_checker.cpp:
   - visitTypeofExpr
   - visitQualifiedType
2. Namespace inconsistencies identified:
   - pryst::pryst::types incorrect nesting
   - Inconsistent use of core:: qualifiers
   - Mixed usage of namespace blocks and using directives

## Next Files to Process:
1. type_registry.hpp (high priority)
2. error.hpp (high priority)
3. error_type.hpp (high priority)
