Pull Request Overview

This PR fixes a parser error handling issue where missing function bodies in function expressions were not being properly reported. The change ensures that function expressions always attempt to parse a body, even when the opening curly brace is missing, allowing the parser to generate an appropriate error message.

Key Changes:

• Modified the condition for parsing function bodies to include function expressions
• Function expressions now always attempt body parsing, enabling error reporting for missing bodies
