> the important thing about destructors is that you know where to find them

The problem isn't that programmers have trouble finding a destructor. The problem is it's not apparent looking at any snippet of C++ code which objects have destructors running additional cleanup logic or other extra code without looking up each class declaration and verifying.

I believe Odin is trying to solve this by forcing the programmer to make this code explicit, but reduce the number of footguns by allowing the programmer to keep the initialization and free close to each other.
