I think occurrences of
 
   x = foo     # set default value
   if cond:
      x = bar

should also count as potential places for a conditional expression,
even though no "else" is involved.  It's a shortcut for

   if cond: x = bar
   else: x = foo

and so instances of it should be included in your "database".
