Even in the podcast transcript it is both.
Actually that's not true, I have another question. The single greatest strength of both C++ and Rust is the destructor: it makes them viable. Its lack is all that keeps me from thinking Zig is something I might want to use. Why doesn't Zig have an analog of the destructor / Drop trait?
I don't have any benchmarks because I don't work on low level code all day, but apparently it can be slow enough that it puts people off using destructors. This isn't a joke.
In fact, some people will not use new/delete. Some people will also go further and not even use malloc but prefer to use the syscalls for getting a block of memory directly from the operating system and managing it completely themselves. These are usually the people who don't use the standard library/libc.
Suggesting destructors slow down execution really is a joke. The joke is on people who believe it. People will grasp at any straw to avoid need to learn anything new.
