Change presentation to avoid uint64 overflow in slashing penalty calculation. (Factor out `EFFECTIVE_BALANCE_INCREMENT` from `validator.effective_balance`.)

Remove another unnecessary list materialization 2019-07-10 17:05:49 -07:00
Alex Stokes b80d6e0495
Avoid unnecessary materialization of list 
There is a realization of a `list` in the `get_unslashed_attesting_indices` helper that is unnecessary.

The functionality in this PR is the same so this change should only really be cosmetic wrt the spec.
