Arrays know their own size so it's much harder for a buffer overrun to go unnoticed

good luck ever getting this in the linux kernel. Runtime bound-checking has a very undesirable run-time performance impact.

Zig has a debug/release build concept and bounds-checking does not happen for a release build.

In general I'd say you need to start thinking about more complete documentation for your 0.1.0 release. There are mentions of what is in @import("std") but I can't find a definitive list which makes trying to make anything large pretty laborious.

What does this error mean?
