            Bug ID: 379961
           Summary: Wrong type for 'or' operator expression
           Product: kdev-python
           Version: git master
          Platform: Debian testing
                OS: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: NOR
         Component: Language support
          Assignee: mail@svenbrauch.de
          Reporter: nicolas.alvarez@gmail.com
  Target Milestone: ---

According to the Python documentation, "The expression "x or y" first evaluates
x; if x is true, its value is returned; otherwise, y is evaluated and the
resulting value is returned."

However, kdev-python thinks 'or' always returns a boolean:

a = "a"
x = a or "foo"

The tooltip indicates 'a' is of type 'str' and 'b' is of type 'bool'. This is
wrong; it should say 'b' is of type 'str'. More generally, the type of 'x or y'
should be 'unsure(type(x), type(y))'.
