Exciting stuff! This feels, at least to me, like a proposal with major<br>
implications – not least because I believe it means that type equality<br>
will now involve some form of term equivalence, and may thus affect<br>
what kind of Core transformations are still type-preserving. Therefore<br>
I would suggest Simon PJ to shepherd this proposal.<br>
<br>
Please guide us to a conclusion as outlined in <br>
