funky 2.5 defgen
This is the new syntax for using the new 2.5 generators with twisted.

@defgen
def foo():
  value = yield someDeferredAction()
  row = yield someDatabaseQuery(value+1)
  yield row['column']

which is an analog of the 'old' way of doing things, like this:

def foo():
  def _increment(value):
    return value+1
  def _getcolumn(row):
    return row['column']
  return someDeferredAction(
  ).addCallback(_increment
  ).addCallback(someDatabaseQuery
  ).addCallback(_getcolumn)

Yay to christopher armstrong for putting this together, yay to PJE for writing the code for python2.5
