And if you _did_, then one of the first lines in your function would
be:

    args = list(args)

Which is obvious to everyone, doesn't modify existing behaviour,
doesn't force everyone without a fetish for change to add unnecessary
cruft to their function signature...

Except, OMG, list() is RETURNING A LIST, which is an OBVIOUS type
constraint. I propose that:

    args = @set list(args)

Will coerce args into a list and then give me a set in return.
