Generates random pairs using elements from a single iterator, where the first element of each pair is less than the second.
The input iterator must generate at least len distinct elements; otherwise, this iterator
will hang.
$$ P((x_0, x_1)) = 2P(x_0)P(x_1). $$
The above formula assumes that the pair is valid, \emph{i.e.} its first element is less than its second. The probability of an invalid pair is zero.
xs must be infinite.
