Description
If I have fn roundtrip<T>, I would think test-fuzz can maintain a separate corpus for each T, and generate an entrypoint for each one. However, I must specify T e.g. #[test_fuzz(generic_args = "String")] and can only provide one type as a list will fail to be parsed by the proc macro.
It would be nice to generate a binary for each generic arg in the list and be able to run all of them without having to replace the type manually. Maybe I am missing a better way to do this...

Research direction
Start by tracing how the #[test_fuzz(generic_args = "String")] proc macro parses and uses its single generic type for fn roundtrip<T>. Determine the intended list syntax and how separate corpora and entrypoints should be generated for each type. Done means a list of generic arguments parses successfully and all corresponding fuzzing binaries can be run without manual replacement.
