You know that you're running into problems with the SPI subsystem on
that one, no?
Identifiers cannot be parameters in SPI_prepare(). So how do you propose
to make that "pretty" and "performant"?
Because the moment, your "pretty" language is out there, be sure users
will kick your behind that whenever they use that "pretty" stuff on
anything but a toy setup, it spirals their servers into a DOS attack state.
