For future reference, it will be called `clone_from_slice` soon (1.78):

    https://doc.rust-lang.org/beta/core/mem/union.MaybeUninit.html#method.clone_from_slice
    https://github.com/rust-lang/rust/issues/79995

This could be a "good first issue", i.e. to replace these if these get
stabilized (which seems likely).

Though that one has to account for panics -- it would be good to check
codegen if we do replace it.

Cheers,
Miguel
