Description

What is your question?

Is there an easy way to pass a custom NamedTuple into the kernel?

From this function, it seems like tuple/list is supported, but that construction would fail for NamedTuple.

Thanks in advance!

Research direction

Start with python/CuTeDSL/cutlass/base_dsl/dsl.py around line 194 and reproduce passing a custom NamedTuple into the kernel. Trace how tuple and list values are handled, then determine whether NamedTuple support has a defined expected behavior; completion requires a clear supported approach or documented limitation with coverage if applicable.
