Indeed, I had no idea there are multiple languages referred to as “APL”.

I feel like most people defending C++ resort to “people shouldn’t use those features that way”. 😅

As far as I can tell, pointer arithmetic was not originally part of PASCAL; it’s just included as an extension in many implementations, but not all. Delphi, the most common modern dialect, only has optional pointer arithmetic, and only in certain regions of the code, kind of like unsafe in Rust. There are also optional bounds checks in many (possibly most) dialects. And in any case, there are other ways in which C is unsafe.
