Another I can only partially refute: If you're having an e-mail discussion
about code, some mailers like to reformat your code into a paragraph.
Needless to say, this is bad for pretty much all code, but pathological for
Python and other languages that use whitespace in a manner distinct from
basic paragraph-filling.

Some alternatives:

   - Use a proper code review tool instead - EG
Rietveld<http://code.google.com/p/rietveld/>.

   - Use a wiki instead - sometimes with a <source lang="python"> tag (EG,
   on Wikipedia <http://en.wikipedia.org/wiki/Binary_logarithm>).
   - Use HTML e-mail and a <pre> tag
      - Except this'll have problems with real <'s and >'s - which are
      common in Python and other languages.
      - You can pipe your Python through this
sed<http://en.wikipedia.org/wiki/Sed>command to deal with real <'s and
>'s
         - sed -e 's/</\</g' -e 's/>/\>/g'
      - Note that this is no more onerous than running code through a code
      beautifier
   - Use a non-borken MUA <http://en.wikipedia.org/wiki/Mail_user_agent>like
   mutt <http://www.mutt.org/> for such communications
   - Mail your code as an attachment.
