In our environment, we have a wrapper which enables optimization by default (-OO). Most commandline tools which have a mode-changing flag such as this, also have a flag to do the opposite ( see: ls -t -U, wget -nv -v,  ).

I'd like to implement one or both of:
1) Add a -D option which is the opposite of -O. python -OO -D gives an optimization level of 1.
2) Honor PYTHONOPTIMIZE = 0. At the least, the man page needs to describe how these two methods interact.
