Bounds checking by default.

Actors, more precisely active objects in Active Oberon, the only one still actively being developed at ETHZ from Oberon linage.

That's odd - I've written a C container library that checks bounds by default.

Are you sure that C doesn't allow you to check bounds?

Absolutely unless you're using a compiler with language extensions for pointer management.

A library isn't the language that is described by the ISO C standard document.

Sure, but the poster didn't ask "what comes with apl and oberon that doesn't come with C", they asked "what do you think apl and oberon can express that C cannot?"

And you absolutely, positively can EXPRESS bounds checking in C. I'm not sure where you heard that this is impossible, but it's probable you misunderstood or that source is wrong.

but that's a high level feature, when people talk about C not being a low level language they mean you can't control/reflect the hardware enough right ? or maybe I'm misguided
