Sure, let's optimize the code. Your code already does quite a lot, so optimizations will primarily focus on reducing redundant calculations, avoiding unnecessary data structures, and streamlining control flow where possible.

Here’s the revised code with improvements for efficiency.



### Optimization Highlights.
1. **Early return with ternary conditional operators**: Simplified the conditions for creating the regular expression pattern.
2. **Regex matching to split expressions - Single iteration**: The logic to add elements to the pattern list is concise and reduces the number of iterations.
3. **Direct dictionary lookup for type patterns**: Avoids multiple `if-elif` checks.
4. **Use of `partition` instead of `split`**: Provides a faster mechanism to separate the name and format in the `_handle_field` method.

This refactoring improves readability and performance by reducing redundant checks and optimizing string operations.
