+## TODO 
+Currently this code is relatively unimplemented things we need to do are
+1. Fully implement all of the types
+2. Make sure these types work properly with infrastructure like `UnallocatedArrays`...
+3. Make sure type promotion works as expected for each `UnallocatedType`
+4. Make a test suite for the module
