The check is made against a boolean value in the C extension, I don't think
that it offers a significant speed-up against the pure python code.
but it offers a simpler (reduced, global) assertion syntax though.

Subject: Re: [Python-ideas] Runtime assertion with no overhead when not active
I currently use the form
<control_flag> and log_function( <msg_expr> )
where <control_flag> is some module variable, usually "DEBUG". I do this
because it is one line, and it ensures the log_function parameters are not
evaluated.
*IF* runtime assertions had a switch so they have no overhead when not active,
how much faster can it get? How expensive is the <control_flag> check?

My logging example would be

if <control_flag>:
log_function( <msg_expr> )

This idea requires the same sort of machinery in python that I was hoping for
to implement the short circuit logging.
