It's the multiple assign which is hard. If you could write

{a,b}=swap(b,a) or massign({a,b},swap(b,a))

then return doesn't need to change. But multiple assign is horrible,
like the sudden English "or" separating the Euphoria code above.
Quickly, what's edge set to in:

{girth,widths,height,uplift,edge,jut,throw}={3,{7,6,5,2},89,2,{3,4,2},9,{3,4}}

OK, so you might know that fairly easily,or not, but you've just read
the line of code, so without looking, what was height just set to?

For something minimalist like swap you just really want a <=>
operator, there is no better way to make it nice&sweet&short. For
anything more complicated, though
	temp=func(a,b)  a=temp[1] b=temp[2]
is justified. I use it alot and it's not so bad if you do that rather
than have [1] & [2] litter the following code. Othertimes I enumerate,
eg
constant COUNT=1, AVERAGE=2   then
 if result[COUNT]> threshold then
	...
	x=result[AVERAGE]*result[COUNT]
