    Usability always trumps performance.

    That's the philosophy of languages like Python, not Ada.

    Ah, this is why Python is totally unusable? (:-))

    I would tend to argue that it is indeed the case that you get dubious
    results when you put usability first. Ada puts
    readability/understandability, maintainability, and consistency first=20 (along
    with performance). Those attributes tend to provide usability, but not at
    the cost of making things less consistent or understandable.

    I wrote an article on this topic a year and a half ago that I wanted to publish on Ada-Auth.org. But I got enough pushback about not being=20 "neutral"
    that I never did so. (I don't think discussing why we don't do things som=
    e
    other languages do is negative, but whatever.) I've put this on RR's blog=

    Dear all,

    Thanks indeed.

    is only one instance where Ada required such repetition. [. . .]

    I wrote a function to increment as a workaround but opinionated Anita=20

    " if X in T'Class then

    T'Class is repeated 3 times."

    Sorry: 2 times.

    With best regards.
