AAAAH! Back, you!
Seriously, I realize those were added, but I was one of the few who saw it
as being an unnecessary degradation of the language. (I know, I know,
"efficiency first". But really, if I was concerned enough about Euphoria's
efficiency to worry about the speed gains in a statement like "x = x + 1"
over "x += 1" (if any), I doubt I'd be using it.)

Yes, I had been referring to it as a function ("swap(a,b)").
I'll admit though, the latter example of the alternatives does look junky
(pardon the pun.) But honestly, I haven't decided. "{a,b}={b,a}" looks almost
alluring, but some part of my being cries out at the apparent placement of a
sequence on the left side of an assignment. Multiple assignment of some sort
("a,b,c = 1" or "a,b,c = 1,2,3") might be desireable, but I think whatever
construct embodies the idea should NOT make use of the sequence brackets for
delimiters.
