assert disabling debug option for numba jit compilation

Any respectable compiler has options for levels of code optimalisation and / or debug mode, that can disable assert statements. The assert statements are very powerful tools for debugging and sanity checking.
Python's default assert disabling options are very cumbersome for the typical REPL / Jupyter notebook data science workflow, since assert statements cannot be disabled / enabled during runtime at will. However for pure python, it does not present too much problem, because of the REPL capability of the language. Though even for pure python it would be good to be able to disable assert statements at will.

For compiled code, asserts are vital for debugging. Hence it would be nice to have a debug option to disable assert statements in the numba jit-ed code, after the debugging process is finished.
