Ordinarily, for 2.x/3.3+ code I would suggest not doing this --
instead, b'...' for bytes, u'...' for unicode, and '...' for native
"string" type (bytes on 2.x, unicode on 3.x). This is the main benefit
of the u'...' syntax addition.
For 3.2, you'll have to do b'...' for bytes, '...' for unicode, and
str('...') for platform-specific strings (bytes on 2.x, unicode on
3.x). It is in good taste to make an alias of str so it's less
confusing, e.g. native_str = str.
So for example, it's __import__(str("foo")), and getattr(foo, str("bar"), baz).
