ok let me explain:
I did not think he/she/anyone would ask the question in the main thread
without trying the interpreter a few times starting it from different
directories.

Because I, as an individual, would not ask this question without running
interpreter from different directories.
and I would look whether I created a py file with the exact same name of a
core module.

And this "simple" mistake had been pointed out by other guys.
The only other reason that came to my mind was this pythonpath.
( and I was dealing with it recently: you may have take a look at the thread
titled 'embedded pyton pythonpath' any answer is appreciated :p  )

yeah same result: bogus re. but from a different way: not user's re but
created by someone else in another directory.
