I would favor ~.!.1. No mnemonic value, but less likely to be forgotten.
What is your fast algorithm?

Suppose that ~. (and perhaps some relatives) can be implemented much

a special combination to invoke such an algorithm? If so, what would
be better?
Most special combinations would not incur a performance penalty vs an
alternate expression of the same semantics on an implementation which
did not recognise special combinations. But I cannot think of any way
of expressing ambivalence regarding the order of a result other than
shuffling it.
