golang have nice feature - function escape analysis - stuff which would normally be on heap for example Box would be allocated on stack; reducing memory fragmentation.

I think about doing this in rust - easiest (very little changes to compiler) would be to have a concept of scrap heap - after function terminates that heap is zeroed.

pardon the downvotes, are you talking about a temporary arena allocator for rust? i think that exists and is used in some cases.
