def transform_numbered_params(source)
  result = source.dup

  # Simple approach: replace all _1 with it when it's the only numbered param in scope
  # For complex cases with _2+, we'd need proper parsing
  # For now, do a global replacement if _2 etc are not present
  if result.match?(/\b_[2-9]\b/)
    # Has multiple numbered params - need to convert to explicit params
    # This is a complex case that requires proper block parsing
