raised an error.
Replace them with using concrete types API that never fails if appropriate.

Reduce load factor (from 66% to 60%) to improve effectiveness of linear probing.
...
Decreased density gives better collision statistics (average of 2.5 probes in a
full table versus 3.0 previously) and fewer occurences of starting a second
possibly overlapping sequence of 10 linear probes. Makes resizes a little more
frequent but each with less work (fewer insertions and fewer collisions).

Remove unnecessary variables.

* so->used never gets changed during a resize
* so->filled only changes when dummies are present and being eliminated

Responsibility for argument checking belongs in set.__init__() rather than set.__new__().
...
See dict.__new__() and list.__new__() for comparison. Neither of those examine or touch
args or kwds. That work is done in the __init__() methods.
