It was added, but immediately after the rest. I was just quickly refreshing my memory on what Rust was doing. I think it is a terrible design.

If you want special function which protects you from errors in specific scenarios it is easy enough to do this in C. But I do think the C defaults are actually ok and having all the wrapper functions and boiler plate has its downsides too (What I would admit is bad in C are the default warning modes in C compilers).
