Subkernels behave in most part as regular kernels, they accept arguments and can return values. However, there are few caveats:
- they do not support RPCs or calling subsequent subkernels on other devices,
- they do not support RPCs,
- they do not support DRTIO,
- their return value must be fully annotated with an ARTIQ type,
- their arguments should be annotated, and only basic ARTIQ types are supported,

While ``self`` is accepted as an argument for subkernels, it is embedded into the compiled data. Any changes made by the main kernel or other subkernels, will not be available.
Subkernels can call other kernels and subkernels, if they're within the same destination. For a more complex example: ::
