Except there is no error handling for situations when re.search() returns None, so one shouldn't use it anyway (most of the time). Which seems to me like another nice example why one should stay away from this style as much as possible. I am too lazy to be tempted into this nice-example-terrible-production-code world.

Best,

They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety. -- Benjamin Franklin, Historical Review of Pennsylvania, 1759.
