Blair, please, don't give bad advices. The 'double-leading-underscore'
stuff has some side-effects (name-mangling), and is meant to protect an
attribute from accidental overloading. The convention for 'protected'
attributes (which should really be named 'implementation attributes') is
a *single* leading underscore.

p in 'onurb at xiludom.gro'.split('@')])"
