Looks good to me, just needs the test fixing up for the simulator.

Greptile Overview

Greptile Summary

Expands CUDA print functionality to support nested tuples and mixed element types.

• Added types.Tuple registration to tuple_print_impl alongside existing UniTuple support
• Replaced hardcoded int64-only printing with recursive print_item calls for each element type
• Handles single-element tuples with correct Python syntax (x,) vs multi-element (x, y)
• Added test coverage for nested mixed-type tuples (1, ((2, 4), 3.0), (4,), 5) and single-element tuples (1,)

Confidence Score: 5/5

• This PR is safe to merge - it extends existing functionality with proper recursive handling and adequate test coverage.
• The implementation correctly leverages the existing print_item dispatch mechanism for recursive tuple printing. Both Tuple and UniTuple types have a .types property that returns element types, making the unified approach sound. Test cases validate the new functionality.
• No files require special attention.

   logic: printstring_in_tuple_usecase is defined but no test method uses it. Consider adding a test method like:

   def test_string_in_tuple(self):
       output, _ = self.run_code(printstring_in_tuple_usecase)
       lines = [line.strip() for line in output.splitlines(True)]
       expected = ["(a, b)"] * 3
       self.assertEqual(sorted(lines), expected)
