NSArray supports lightweight generics in ObjC. Our extension on NSArray
for map/filter/reduce does not. This change tweaks the interface to
better support generics.
Also, fixes some tests that weren't compiling.
- dictionaryWithObject -> @{key: val}
- objectAtIndex -> a[i]
- numberWithBool/Int/etc -> @1, @(val)
- Reverted friendly fire on ProtocolBuffers
- Did not do ANY other changes (including changes to make more refactorings succeed)
