Should we always use tuples when instantiating them
only once? E.g.
*if* abc *in* ('e', 'f'):

Performance-wise, I don't think it matters much; after all, most time is
spent inside the loop, not in instantiating a list or tuple. Conceptually,
a list often makes more sense (a list would be different items of the same
type, while a tuple represents different properties of the same item).
