[plt-scheme] Development and Debugging

I've written a log module for mzscheme (log4scm),
which has several "log levels". Log levels consist of
'debug, 'info, 'warn, 'error, 'fatal. I can set the level
of logging runtime. If I set it, e.g. to 'warn,  the log
functions for 'debug and 'info will be replaced by
the function I mentioned.

So, the next question is: How will a call to a function
that does nothing impact performance.

Best whishes,

Hans
