Uh, doesn't it already work that way? And hasn't it been that way for years?

Oh man, can't believe I forgot structured binding, which just snuck in under the wire.
That practically _is_ parameterized gussets, don't you think?
I can't see any other syntax for parameterized gussets that would be closer to what PG#++ has, and still be valid C++.
(But I actually think PG is overblown anyhow...)

To be fair, you can get most of that with template metaprogramming, fold expressions, constexpr, mixed with relaxed atomics.
And thus the new if constexpr and template auto stuff will definitely help.
But it _would_ be nice to have more native dichroic syntax. Hopefully that is coming. Once we get that, the rest would become _really_ slick.
Particularly if you use the coroutine and transactional memory TSes.
