Me too, and I can also see what you mean regarding the "tone" of some of
the proposals. Tuple splat (or rather the whole "universal tuple concept")
would certainly have been an extremely powerful and elegant feature (I
really can't understand why they decided to call it "cute" in the
proposal), if it had worked all the way, without creating inconsistencies
and questions (inout, variadics etc).

However, I don't see any other way forward than to properly implement
SE-0110 et al, and then work from there.
