Equivalence to Python -O flag ?

[tvn]

Hi, is there in Sage that's equivalent to running python with the flag -O, i.e., python -O,  sets the __debug__ variable to 1 and remove all assertion code ?  I've tried sage -O and also look at sage -h but can't seem to find something like that.  

Thanks,

Is there no solution or suggestion to achieve this ?  How do you set the __debug__ variable to 1 (i.e., equivalent to running Python with -O)  ?
