> is an Error<T> really more desirable than a segfault? It's only by happy coincidence that it manifests cleanly as a segfault. In the C language, dereferencing NULL causes undefined behaviour, so all manner of peculiar things can happen. This isn't just theoretical nit-picking, it can happen with real code: • Raymond Chen's Undefined behavior can result in time travel (among other things, but time travel is the funkiest), https://devblogs.microsoft.com/oldnewthing/20140627-00/?p=63... • John Regehr's A Guide to Undefined Behavior in C and C++, Part 1, https://blog.regehr.org/archives/213 (ctrl-f for A Fun Case Analysis) |
