As a directly interned string.  Indirect interning is irrelevant to this
benefit.

Don't argue about this, run the patched code <wink>:  it will tell you
directly whether ii is doing you any good.

Again it doesn't really matter when you call it; if the indirect interning
optimization is doing you any good, it will be because of stuff Python is
doing under the covers.
