[Python-ideas] Runtime assertion with no overhead when not active

[Kyle Lahnakoski]

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?
