Use them as you want.  This change came about because .index was 
included in the 3.0 Sequence ABC (abstract base class) and tuple was 
included as a sequence, so .... something had to give.  The result was 
tuple getting the full suite of immutable sequence methods.  And then 
there was no good reason to not backport ;-).
