We have some code to do exactly this:
https://github.com/snapframework/snap-core/blob/master/src/Snap/Internal/Deb...
You set a DEBUG environment variable to turn debugging output on. We
should probably split this code out into its own package.

Hi,
I have a program with a debug flag in it (Strangely I've yet to be able to write bug-free code). I'd like to change the state of the debug flag based on command line args.
I looked at IOVar but that would cause all the pure procedures to get swallowed by the IO Monad.
Is a better way to get this behavior ?
Thanks,
Brian
