- Are the requested number of elements the same?
- Are the requested dimension values all non-negative integers?
- If there is a missing dimension, calculate this value and make sure it is an integer.
- Can the result be a shared data copy? (e.g., for a full matrix)
- Will the result need to be a deep data copy? (e.g., for a sparse matrix)
- Etc.

We don't distribute the source code for that built-in function.
