A short explanation of what this is all about might make that info a
bit more useful:
The compiler makes illegal optimizations when you have structs on the
stack and pass them by reference to a function that modifies them.
(EEL does quite a bit of just that when dealing with the tagget value
structs used for dynamic typing.)
