Fun fact: As a challenge I wrote an entire slice library without testing it until the whole thing was done, then ran it through sanitizers to see how many errors would have slipped through. It was a *fantastic* library. It was *absolutely useless* because C invariants are fake. I hate it here

What I'm trying to say is "Please please I want a built-in slice type." (I want a built-in slice type in C++ too but I'm *almost* ok with itr pairs and/or std::span)

what testing lib did you use? I'm looking for one in C and there's like a bazillion options
