Many interesting discussion points in the video. It seems Sean 
Baxter's "circle" C++ compiler is opening some eyes.

A quick scan produced an older critique of circle wrt another C++ 
proposal: 
http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2020/p2062r0.pdf.  Those authors seem to embrace crippling, IMO, scope restrictions that circle does not.

If you've looked at circle's capabilities and would care to 
comment wrt D, I think we'd all benefit.

Separately, many thanks for your great work in D.
