I’ve recently been writing personal code that leaks like a sieve. It’s just not worth my time to find every leak when the lifetime of the process is finite and short and it will only ever run on a machine with gigs of memory. I haven’t thought through your question enough but maybe a situation where memory usage would be super high if waiting until the end of scope? I’m probably trying to hard to come up with a situation but I have a gut feeling that freeing mid scope is important under certain circumstances to keep the code simple and understandable.
