And I think most people who have been programming in python for any length
of time develop some form of what you are describing.

Oh, interesting. Such an option could also alter -O and -OO to keep assert
statements.

I'd love to see that idea elaborated further, as there are a variety of
questions around how it might work in practice (Compile time constant like
__debug__? Always False builtin shadowed in the main module? If it works
like __debug__ and/or affects -O and -OO, does it need a new naming
convention in the pycache directory?)

Cheers,
Nick.
