.. function:: compress(data, selectors)

Make an iterator that filters elements from *data* returning only those that
have a corresponding element in *selectors* that evaluates to ``True``.
Stops when either the *data* or *selectors* iterables has been exhausted.
have a corresponding element in *selectors* is true.
Stops when either the *data* or *selectors* iterables have been exhausted.
Roughly equivalent to::

def compress(data, selectors):
# compress('ABCDEF', [1,0,1,0,1,1]) → A C E F
return (d for d, s in zip(data, selectors) if s)
return (datum for datum, selector in zip(data, selectors) if selector)
