It’s a temporary leak. My point is that it’s an actual side effect, unlike how in C it has no effect whatsoever if the value is ignored. In a language where destruction of an object often releases external resources (C++, for example, or Python or Rust to a lesser extent), this effect would be more dramatic. Imagine someone doing this in Python: def func(): f = tmpfile(…) err = do something return f, err This style would be absurd and wrong — it keeps f alive to long.
