Crazy, nutty, wacky idea...

I'd like some syntax sugar for tuples in D (especially for their
unpacking), that syntax goes against one of the most natural ways to
define tuples. So it's not a good idea.
It is highly unlikely that D will ever adopt that syntax for tuples,
due to the previously much-discussed comma operator (which, while
uncommon, is useful at times). I believe the syntax that came out on
top in earlier discussions was the upended hamburger bun, or banana
syntax:
(| float f, string s |) foo = (| 1.2, "Eh, whut?" |);
Here's a crazy idea:
auto foo = tuple(1.2, "Eh, whut?");
Is this particular case, a built-in syntax buys you nothing, as you
demonstrate. I think that the case that Bearophile is always looking for is
something like this:
int i;
float f;
(i, f) = tuple(5, 2.2);
scatter(tuple(5, 2.2), i, f);
The more difficult construct is:
auto (i, f) = tuple(5, 2.2);
Walter and I discussed a language change to allow that.
