def viper(func:Callable) -> Callable:
    """
    The Viper code emitter is not fully compliant. It supports special Viper native data types in pursuit of performance. 
    Integer processing is non-compliant because it uses machine words: arithmetic on 32 bit hardware is performed modulo 2**32.
    Like the Native emitter Viper produces machine instructions but further optimisations are performed, substantially increasing 
    performance especially for integer arithmetic and bit manipulations.

def native(func:Callable) -> Callable:
    """
    This causes the MicroPython compiler to emit native CPU opcodes rather than bytecode. 
    It covers the bulk of the MicroPython functionality, so most functions will require no adaptation.
