    Make benign non-determinism in pretty-printing more obvious · 0f96686b
    niteria authored
    This change takes us one step closer to being able to remove
    `varSetElemsWellScoped`. The end goal is to make every source
    of non-determinism obvious at the source level, so that when
    we achieve determinism it doesn't get broken accidentally.
