Unify numeric semantics around longs, with throw on overflow. Allow numeric literals to be primitive initializers. Canonicalize boxing of integers, if it fits in int, is Integer, else Long, thus primitive coercions can't be used to get particular boxed types, use Long/valueOf etc. Ask for BigIntegers if you want arbitrary precision, new literal number format - append 'N' for BigInteger. BigIntegers do not reduce automatically, are contagious. New particular names for unchecked ops - unchecked-xxx-int or unchecked-xxx-long. You should need far fewer hints for primitive perf, and avoid int casts and any casting of numeric literals, see:
