About =E2=80=98flatten=E2=80=99 specifically, I feel like it=E2=80=99s not =
a good sign in terms
of programming style when we end up using it (though we=E2=80=99d need to s=
tudy
these specific use cases), so I=E2=80=99m reluctant to =E2=80=9Cstandardizi=
ng=E2=80=9D it.  :-)

Yes, sounds like a good idea!

Thanks,
