[Python-ideas] Dynamic code NOPing

[Jasper St. Pierre]

if __debug__:
    log(factorial(2**15))

Running python with -O will squash this statement. To have something
inline, you could also abuse assert statements to do the job.

def debug_log(x):
    log(x)
    return True

assert debug_log(factorial(2**15))

In optimized builds, the statement will be removed entirely.
