I'm not sure if the lazyDict approach applies, but I'm hitting a much
simpler (IMO) issue that I've reported
at https://github.com/elm-lang/html/issues/21.
I'm honestly surprised that no one has run into it yet, specially since the
documentation for `key` in 0.16 specifically provides this exac
Here are two examples were key is needed
https://langrisa.eu/virtual-dom-pitfalls/ . I don't understand the new lazy
proposal so i can't judge if it would work well in these cases. Why can't
the compiler just infer where this is needed? Thinking about key is a HARD
problem for your brain.

I was using virtualdom key for two things, both of which I cannot do in
0.17.
1. Instructing virtual-dom whether or not to reset scrolling-state of an
element. Try it out here: https://debois.github.io/elm-mdl/: Scroll to the
bottom, then switch tab. Because virtual-dom is re-using the div cont
