Language note: postfix operator, not postscript operator. Postscript is
like a footnote/endnote.

For the proposal, the symmetry with && is definitely nice.

But it has two unfortunate interactions with logical AND. One you pointed
out:

a&&(b)

Another is:

f(xs&&...)
f((xs&&...))

Those two expressions do very different things - the first would forward
all the arguments, the second folds over logical AND and is passing a bool.
This isn't an ambiguous parse, but it's still a bit problematic from the
human comprehension perspective.
