  • There’s the peritoneum which lines the abdominal cavity.

    It’s got a bunch of blood vessels to exchange chemicals so it’s common to do kidney dialysis right into the abdominal cavity instead of the blood directly. Unlike hemodialysis, the machines can be taken home and operated by the patient.

    And in vaginoplasties when they don’t have enough tissue to do just a penile inversion, they can now pull through the peritoneum to help construct the vaginal canal instead of doing a colon graft.

    The buffalo thing pisses me off the most. Entire cultures are defined by that animal and it’s incredibly significant to the history of the prairies and the continent as a whole. So it seems to me pretty disrespectful to go to these people and go “um actually what you’ve been calling this animal for centuries is wrong actually because Linnaeus or whatever”

    It’s worth noting that a number of languages comparable C in use case and performance (including its predecessors COBOL, Fortran and ALGOL) start indexing at 1 just fine because they have proper array types and don’t make heavy use of pointers poking and peeking wherever they like (eg by using references instead).

    Decoupling indices from memory offsets doesn’t get in the way of performance and actually often allows better optimization because the compiler knows you aren’t sharing pointers between arrays or some other shenanigans; see Fortran, the GOAT of fast array processing. This also allows improved type safety and thus memory safety; see index types in Ada/SPARK and the fact that it’s the only ‘legacy’ language that’s gotten comprehensive compile-time memory safety analysis (though the latter is moreso from the less willy-nilly pointers in general)
