Since no one seems to be interested to review this patch, I did that
myself.  I have two comments:

Typo: should be "look", not "looks".

This function's doc string looks strikingly different from the rest of
the functions you wrote: not as detailed and clear as the rest.  Can
you rework it to be more in line with the rest of the functions?

With those minor issues fixed, I will push your changes.

Thanks.
