ER: Pointer needs a #cast for untyped pointers

Description

We need a method to change the type of a Pointer object. For example: 

framework 'CoreData'

NSPersistentStoreCoordinator.alloc.init
ptr = NSPersistentStoreCoordinator.registeredStoreTypes[NSSQLiteStoreType].pointerValue
puts ptr.inspect
klass = ptr[0].migrationManagerClass
puts klass.inspect

...results in: 

#<Pointer:0x40074e420>
undefined method `migrationManagerClass' for 40:Fixnum (NoMethodError)

I added the Pointer#cast! method in r3945 + specs in r3946. However in your case, I recommend using the following instead: 

framework 'CoreData'

val = NSPersistentStoreCoordinator.registeredStoreTypes[NSSQLiteStoreType]
klass = val.nonretainedObjectValue
klass.migrationManagerClass
