The implementation is such that it is pretty easy to add the method to
other file-like objects. It is also easy to use the xreadlines module to
get the same behavior for objects that do not have the method.
Essentially, file.xreadlines is implemented like this:
def xreadlines(self):
import xreadlines
xreadlines.xreadlines(self)
Any object can add the method similarly.
