Quote of the Week
As the tradeoffs in software engineering change over time, so does the ideal solution. Some 40 years ago when the first C standards were written down, by people no less competent than those that work on Rust today, the design of the language and the list of behaviours not defined likely made much more sense in context of back then than they do right now. It is not all that unlikely that some years down the line the choices made by Rust won't make all that much of sense as they do today, too.
Thanks to Kill The Mule for the suggestion!
