I'm not sure that `y = list(x)' returns `y' different than `x', if `x' is
already a list, in which case the functions above would mutate operands,
which is not welcome.  Maybe (?) it would be safer to write:

def sort(x):
	y = x[:]
	y.sort()
	return y

def reverse(x):
	y = x[:]
	y.reverse()
	return y
