Expansion of the __debug__ and pass concepts

[Janko Hauser]

Have you tried to use assert? It looks for a logical expression, I
have note tested this, but I think the expression evaluation is
skipped if python runs with -O. Yeah I think it the case.

import time

def bigtest():
    time.sleep(10)
    return 1

a=time.time()
print '0'
assert bigtest() == 1
print time.time()-a

gives:
@porto >python test_a.py
0
9.99659597874
@porto >python -O test_a.py
0
0.0057909488678
