If you want Perl, you know where to find it: in Python!  Here's how:

def sort(x):
	y = list(x)
	y.sort()
	return y

def reverse(x):
	y = list(x)
	y.reverse()
	return y

>>> y
[1, 2, 17, 4, 5]
>>> reverse(sort(y))
[17, 5, 4, 2, 1]

The Python way is probably clearer and more efficient, though.

Complex numbers are immutable.  Dunno why.  Maybe so they're like other
numbers.

By the way, what's a Iowegian, and how do you pronounce it?
