2025-01-26	reduce `Box::default` stack copies in debug mode	Joshua Wong	-1/+4
	The `Box::new(T::default())` implementation of `Box::default` only had two stack copies in debug mode, compared to the current version, which has four. By avoiding creating any `MaybeUninit<T>`'s and just writing `T` directly to the `Box` pointer, the stack usage in debug mode remains the same as the old version.
