0. Feature Discussion

statsmodels
- should a user want to use Numba to accelerate parts of some package e.g. statsmodels
- Do we need to create a page on how to take Numba as a dependency?
  - numba @jit as an optional dependency that aliases to a nop
    - njit function bodies
  - overload packages
    - Valid: Project exits to overload function for package X OR
    - Valid: Project overloads its own functions
    - Not valid: overloading functions for some other package that is not owned
Developer onboarding:
- Document how new targets are added
  - Two levels:
    - How user interact with the new target? Most of the effort is here and it is not really dependent on Numba.
    - How target code is lowered? Some changes to customize codegen and calling convention.
Need to start an issue talking about how to integrate with C++ (and what that even means)
