⚡️ Speed up function function_kind by 52%

Here are the main issues and opportunities for speed from your code and profile.

1. **Pointless Reverse For Loop:**  
   ```python
   for _i in range(len(parents) - 1, -1, -1).
       continue
   ```
   This loop does absolutely nothing and should be deleted.

2. **Repeated List/Attr Lookups:**  
   - `parents[0].type` is accessed up to three times.  
   - You do two membership tests for function types with a literal `in ["FunctionDef", "AsyncFunctionDef"]` (slow linear scan).  

3. **Decorator Search:**  
   - Instead of scanning all decorators, you can hoist checks and return ASAP.
   - Use a set for faster comparison (`{"classmethod", "staticmethod"}`).

Here is the rewritten, faster code.



**Summary of speedups:**
- Removed the pointless loop (`for _i in ...: continue`)
- Reduced repeated attribute/membership lookups
- Used early returns and a set for quick decorator name tests
- No change to function signature or result; all comments preserved since only the removed code was nonfunctional

**This version will run markedly faster.**
