neither does for bounds checking. expensiveness does not matter so much in the debug version. > As has been said, multiple times, UTYPE_MAX is not a valid index, and that > is not because of the open-interval on the right.

"length", aka "$") and this is exactly why mentioning "$" as "length" instead of "last element" is inconsistent when you write a[0..$] (the second index is, *with this syntax* UTPE_MAX+1 and is not representable) > But, it's not really important anyways.

I do not much use it anyway. My job (both work and teaching, is C and OpenCL). What I was doing was to recommend it as next language to my students, when they ask about what OOP to learn (they had some choices, among C++ and Java). I find it very difficult to further recommend a language that I do not believe in. Well, I still have two weeks to think about that, semester ends on June 20 (exam of C).
