[slf4j-user] Expressions on log statements to avoid log guading

[Chris Pratt]

At the moment, you still have to use Anodyzed as a wrapper around SLF4j,
but I'm planning on trying to integrate it better when I get the time.  At
this point, I don't know when that will be since time always seems too
short for all the things I'd like to get done.
