Issue
Add a strict option to sort_together() A *strict* option would detect data size mismatches. This would avoid silently dropping data: ``` >>> iterables = [(4, 3, 2, 1), ('a', 'b', 'c')] >>> sort_together(iterables) [(2, 3, 4), ('c', 'b', 'a')] ```
Files to edit
  • more_itertools/more.py
Approach
1. Locate the sort_together() function definition in more_itertools/more.py 2. Add a 'strict' parameter (default False for backward compatibility) 3. When strict=True, check all iterables have equal length before processing 4. If lengths differ, raise ValueError with a clear message 5. Update the type stub in more_itertools/more.pyi if present

Finish summary
Added a `strict` parameter to `sort_together()` function. When `strict=True`, the function validates that all iterables have the same length and raises `UnequalIterablesError` if they differ. Defaults to `False` for full backward compatibility. Updated the type stub in `more_itertools/more.pyi` as well. All 534 tests pass.
