Not really. You would have to either wrap any standard library types in newtypes with ManuallyDrop implemented or (for some) use a custom allocator. And if you want to free some things in one go but not others that gets much harder, especially when you look at how easy a language like zig makes it.

And if you intentionally leak everything it is onerous to get the borrow checker to realize that unless you use a leaked box for all declaration/allocations, which introduces both friction and performance regressions (due to memory access patterns) because the use of custom allocators doesn’t factor into lifetime analysis.

(Spoken as a die-hard rust dev that still thinks it’s the better language than zig for most everything.)
